Why does regular expression ! doesn't work?
In my header_checks file I got
!/^Subject:.*NotBot.*/ REJECT fuck off
In my master.cf I use the cleanup daemon for checking
cleanup unix n - n - 0 cleanup
-o header_checks=pcre:/etc/postfix/header_checks
when I connect to stmpd via telnet to test (Good Subject) I get this
220 test.com ESMTP Postfix
HELO www.test.com
MAIL From: <test#test.com>
RCPT To: <test#test.com>

250 2.1.0 Ok
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>

550 5.7.1 fuck off
But Bad Subject's also work
220 example.com ESMTP Postfix

.
550 5.7.1 fuck off
Fixed it! was pretty easy..
the check_headers is checked for every information in the mail.. so you need to use if/endif to check only Subject: field.
if /^Subject:/
!/^Subject:.*NotBot.*/ REJECT fuck off
endif
Dumb spammers suspended my email account due to abusing my open stmp port.

I am building a web application in the nim programming language and recently wanted to start implementing features regarding sending mails.
Nim has a library std/smtp for this that comes with some pretty simple examples for using both starttls and ssl.
For that purpose I created a dummy mail address on a local mail service provider to play around a bit and can't get it to work, despite following the examples as closely as I could.
Here the code I used:
import std/[smtp]
let smtpServerName = "smtp.web.de"
let startTlsportNumber = 587
let un = "dummymail" # replace with actual username
let pw = "dummypw" # replace with actual pw
let target = "bla#mailinator.com"
#StartTLS code block - Have either this or the SSL code block commented in, not both
let smtpConn = newSmtp(debug=true)
smtpConn.connect(smtpServerName, Port startTlsportNumber)
smtpConn.startTls()
#SSL code block - Have either this or the startTLS code block commented in, not both
# let sslPortNumber = 465
# let smtpConn = newSmtp(useSsl = true, debug=true)
# smtpConn.connect(smtpServerName, Port sslPortNumber)
var msg = createMessage(mSubject = "Hello from Nim's SMTP",
mBody = "Hello!.\n Is this awesome or what?",
mTo = #[target])
smtpConn.auth(un, pw)
smtpConn.sendmail(un, #[target], $msg)
With startTLS this causes a runtime error as the server sends back a 503 response on smtpConn.startTls:
S:220 web.de (mrweb105) Nemesis ESMTP Service ready
C:HELO smtp.web.de
S:250 web.de Hello smtp.web.de [46.183.103.17]
C:STARTTLS
S:503 Bad sequence of commands
C:QUIT
/home/philipp/dev/playground/src/playground.nim(11) playground
/usr/lib/nim/pure/smtp.nim(246) startTls
/usr/lib/nim/pure/smtp.nim(226) checkReply
/usr/lib/nim/pure/smtp.nim(110) quitExcpt
Error: unhandled exception: Expected 220 reply, got: 503 Bad sequence of commands [ReplyError]
With SSL this causes a runtime error as the server sends back a 503 response on smtpConn.connect:
S:220 web.de (mrweb005) Nemesis ESMTP Service ready
C:HELO smtp.web.de
S:503 Bad sequence of commands
C:QUIT
/home/philipp/dev/playground/src/playground.nim(15) playground

Error: unhandled exception: Expected 250 reply, got: 503 Bad sequence of commands [ReplyError]
I've triple checked the ports, the service provider states explicitly that 587 is the port for startTls and 465 for SSL. I compile on Arch Linux with -d:ssl in both cases, so that shouldn't be an issue either.
Trying the same with google-mail it all worked out, but I am slightly annoyed that this didn't work with my original mail provider.
Googling the error for a bit and looking at other questions of other programming languages, the error seems to be related to authentication? Which is weird, because I thought authentication starts after I made the connection secure with startTls. This looks to me like I'm using the std/smtp library wrong, but I don't quite see where. Does anyone here see the issue?
The server doesn't like the HELO that std/smtp uses, it needs EHLO:
$ telnet smtp.web.de 587
[ ... ]
220 web.de (mrweb105) Nemesis ESMTP Service ready
HELO smtp.web.de
250 web.de Hello smtp.web.de [92.191.80.254]
STARTTLS
503 Bad sequence of commands
$ telnet smtp.web.de 587
[ ... ]
220 web.de (mrweb006) Nemesis ESMTP Service ready
EHLO smtp.web.de
250-web.de Hello smtp.web.de [92.191.80.254]
250-8BITMIME
250-SIZE 141557760
250 STARTTLS
STARTTLS
220 OK
So you can get the Nim dev version with this patch, or copy-paste the patch code into your program while it doesn't reach the stable:
import std / [net, strutils, asyncnet, asyncdispatch]
proc recvEhlo(smtp: Smtp | AsyncSmtp): Future[bool] {.multisync.} =
## Skips "250-" lines, read until "250 " found.
## Return `true` if server supports `EHLO`, false otherwise.
while true:
var line = await smtp.sock.recvLine()
echo("S:" & line) # Comment out this if you aren't debugging
if line.startsWith("250-"): continue
elif line.startsWith("250 "): return true # last line
else: return false
proc ehlo*(smtp: Smtp | AsyncSmtp): Future[bool] {.multisync.} =
# Sends the EHLO request
await smtp.debugSend("EHLO " & smtp.address & "\c\L")
return await smtp.recvEhlo()
proc connect*(smtp: Smtp | AsyncSmtp, address: string, port: Port) {.multisync.} =
smtp.address = address
await smtp.sock.connect(address, port)
await smtp.checkReply("220")
let speaksEsmtp = await smtp.ehlo()
if speaksEsmtp:
await smtp.debugSend("STARTTLS\c\L")
await smtp.checkReply("220")
let smtpConn = newSmtp(debug=true)
smtpConn.connect("smtp.web.de", Port 587)
Notice that you need to avoid the call to startTls because the unpatched version does a HELO that would raise another 503, so we send the STARTTLS at the end of our modified connect.
I've noticed that you need to modify your local smtp.nim file to make sock field for SmtpBase object public for this to work. The file is at nim-1.6.6/lib/pure/smtp.nim and you need to change:
62 sock: SocketType
to
62 sock*: SocketType
So it might be better to just patch the whole smtp.nim local file with the code linked above.
Does smpt.gmail.com change the MAIL TO property of an E-Mail? I sent one with these settings with ssl:
MAIL FROM:<someRandomNotExistingEmail#bla.com>
RCPT TO:<myRealGmail#googlemail.com>
DATA
From:<someRandomNotExistingEmail#bla.com>
To:<someOtherRandomNotExistingEmail#blabla.com>
Subject: Hello
Content of E-Mail.
.
250 2.0.0 OK - gsmtp
QUIT
I received the E-Mail, but instead of <someRandomNotExistingEmail#bla.com> the source was <myRealGmail#googlemail.com>, does Google change fake MAIL FROM Headers?
I want to use telnet to send an e-mail with SMTP. It seemed that I had connect to the mail service successfully. And the message had been put in the queue too. But why did the SMTP service failed to send the message to the received address?
When I searched the solution by the internet, someone had said that firewall should paid it. But I have no idea about the relationship between the firewall or antivirus software and telnet.
This is my command:

451 Timeout.
By the way, I tried it both on Windows 10 and Ubuntu-15.10. And both of them failed with the same question.
Finally, I found where I was wrong.
In my previous case,I failed to send a e-mail with the above code.I had succeeded in connecting with the SMTP server, and everything worked except the "Timeout" response. Actually, the "Timeout" didn't mean I failed to send a e-mail but lose the TCP connection. Hours Later, I login my e-mail, which was used for sending, finding that I receive a mail. The mail told me the e-mail I sent hours before with telnet was given back, failing to post. So it meant that the reason was hardly because of my telnet client, but in server or something else.
Finally, I found that it was because of my mail format. In my previous code, after I sending keyword -- "data", I immediately send the content.
data
354 End data with <CR><LF>.<CR><LF>
subject: test
to:<517447201#qq.com>
from:<knowmyheart#sina.cn>

When I changed it to this, it worked.

to:<517447201#qq.com>
from:<knowmyheart#sina.cn>
Testttttttttttttt!
.
250 ok queue id 6744281442287
Notice that the difference between the codes is the empty line before the content in this mail. "subject", "to" and "from" are the headers. Between the header and the content, there must be an empty line.
Similarly, the headers in mail can be ignored. The code is like this:
data
354 End data with <CR><LF>.<CR><LF>
Testttttttttttttt!
.
250 ok queue id 6744281442287
451 Timeout.
Even if there is a "Timeout", it affect nothing but break the tcp connection between localhost and smtp server.
I am getting SMTP Authentication Failure on the server and the mail is getting send via the server SMTP only...
It appears to be a server configuration or related problem, but I am not sure.
This is the debug details:

While testing from my local system, this works and the email is being sent via sendgrid.me
Again, This may not be a SendGrid Problem, but if you have faced similar issue, Can you please tell me what is the problem here?
I am using CentOs and I have cPanel in the server. I believe we are using EXIM for mail server.
For anyone that comes across this in future and are using cpanel/whm, you need to 'disable' this option under 'SMTP Restrictions' in WHM.
I was able to resolve this.
The issue was my server was not allowing the use of external SMTP and using its own SMTP server. I changed the settings and now it works fine.
I am using centos 7 Finally it works!
I was getting this issue(tail -f /var/log/mailog):
to=<usmanali#example.com>, relay=smtp.sendgrid.net[169.45.113.201]:587, delay=0.3, delays=0.05/0.07/0.16/0.02, dsn=5.0.0, status=bounced (host smtp.sendgrid.net[169.45.113.201] said: 550 Unauthenticated senders not allowed (in reply to MAIL FROM command))
Then i changed file /etc/postfix/main.cf in this way that added following lines into end of file
mtpd_sasl_local_domain = $myhostname
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

smtp_sasl_security_options = noanonymous
smtp_tls_security_level = may
header_size_limit = 4096000
relayhost = [smtp.sendgrid.net]:587
Then Installing postfix missing module dependency using:
sudo yum install cyrus-sasl cyrus-sasl-lib cyrus-sasl-plain
Then restarting postfix
sudo systemctl restart postfix.service
For educational purposes, I need to send an email through an SMTP server, using SMTP's fundamental and simple rules.
I was able to do that using smtp4dev. I telnet localhost 25 and and commands are:
I want to do the same thing, using Gmail SMTP server. However, it requires authentication and TLS. I can't figure out how to do that for Gmail. Here's a screenshot of telnet smtp.gmail.com 587:
I searched and found many links including Wikipedia's article about STARTTLS command. But I'm not able to use TLS and authenticate to Gmail's SMTP server using command line (or sending commands myself in programming languages). Can anyone help?
to send over gmail, you need to use an encrypted connection. this is not possible with telnet alone, but you can use tools like openssl
either connect using the starttls option in openssl to convert the plain connection to encrypted...
openssl s_client -starttls smtp -connect smtp.gmail.com:587 -crlf -ign_eof
or connect to a ssl sockect directly...
openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof
EHLO localhost
after that, authenticate to the server using the base64 encoded username/password
AUTH PLAIN AG15ZW1haWxAZ21haWwuY29tAG15cGFzc3dvcmQ=
to get this from the commandline:
echo -ne '\00user#gmail.com\00password' | base64
AHVzZXJAZ21haWwuY29tAHBhc3N3b3Jk
then continue with "mail from:" like in your example
example session:
openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof
[... lots of openssl output ...]

Unfortunately as I am forced to use a windows server I have been unable to get openssl working in the way the above answer suggests.
However I was able to get a similar program called stunnel (which can be downloaded from here) to work. I got the idea from www.tech-and-dev.com but I had to change the instructions slightly. Here is what I did:
Install telnet client on the windows box.
Download stunnel. (I downloaded and installed a file called stunnel-4.56-installer.exe).
Once installed you then needed to locate the stunnel.conf config file, which in my case I installed to C:\Program Files (x86)\stunnel
Then, you need to open this file in a text viewer such as notepad. Look for [gmail-smtp] and remove the semicolon on the client line below (in the stunnel.conf file, every line that starts with a semicolon is a comment). You should end up with something like:
[gmail-smtp]
client = yes
accept = 127.0.0.1:25
connect = smtp.gmail.com:465
Once you have done this save the stunnel.conf file and reload the config (to do this use the stunnel GUI program, and click on configuration=>Reload).
Now you should be ready to send email in the windows telnet client!
Go to Start=>run=>cmd.
Once cmd is open type in the following and press Enter:
telnet localhost 25
You should then see something similar to the following:
220 mx.google.com ESMTP f14sm1400408wbe.2
You will then need to reply by typing the following and pressing enter:
helo google
This should give you the following response:
250 mx.google.com at your service
If you get this you then need to type the following and press enter:
ehlo google
This should then give you the following response:
250-mx.google.com at your service, [212.28.228.49]
250-SIZE 35651584
250-8BITMIME
250-AUTH LOGIN PLAIN XOAUTH
250 ENHANCEDSTATUSCODES
Now you should be ready to authenticate with your Gmail details. To do this type the following and press enter:
AUTH LOGIN
This should then give you the following response:
334 VXNlcm5hbWU6
This means that we are ready to authenticate by using our gmail address and password.
However since this is an encrypted session, we're going to have to send the email and password encoded in base64. To encode your email and password, you can use a converter program or an online website to encode it (for example base64 or search on google for ’base64 online encoding’). I reccomend you do not touch the cmd/telnet session again until you have done this.
For example test#gmail.com would become dGVzdEBnbWFpbC5jb20= and password would become cGFzc3dvcmQ=
Once you have done this copy and paste your converted base64 username into the cmd/telnet session and press enter. This should give you following response:
334 UGFzc3dvcmQ6
Now copy and paste your converted base64 password into the cmd/telnet session and press enter. This should give you following response if both login credentials are correct:
235 2.7.0 Accepted
You should now enter the sender email (should be the same as the username) in the following format and press enter:
MAIL FROM:<test#gmail.com>
This should give you the following response:
250 2.1.0 OK x23sm1104292weq.10
You can now enter the recipient email address in a similar format and press enter:
RCPT TO:<recipient#gmail.com>
This should give you the following response:
250 2.1.5 OK x23sm1104292weq.10
Now you will need to type the following and press enter:
DATA
Which should give you the following response:
354 Go ahead x23sm1104292weq.10
Now we can start to compose the message! To do this enter your message in the following format (Tip: do this in notepad and copy the entire message into the cmd/telnet session):
From: Test <test#gmail.com>
To: Me <recipient#gmail.com>
Subject: Testing email from telnet
This is the body
Adding more lines to the body message.
When you have finished the email enter a dot:
.
This should give you the following response:
250 2.0.0 OK 1288307376 x23sm1104292weq.10
And now you need to end your session by typing the following and pressing enter:
QUIT
This should give you the following response:
221 2.0.0 closing connection x23sm1104292weq.10
Connection to host lost.
And your email should now be in the recipient’s mailbox!
As no one has mentioned - I would suggest to use great tool for such purpose - swaks

I have been using swaks to send email notifications from nagios via gmail for last 5 years without any problem.
Based on the existing answers, here's a step-by-step guide to sending automated e-mails over SMTP, using a GMail account, from the command line, without disclosing the password.
Requirements
First, install the following software packages:
Expect
OpenSSL
Core Utils (base64)
These instructions assume a Linux operating system, but should be reasonably easy to port to Windows (via Cygwin or native equivalents), or other operating system.
Authentication
Save the following shell script as authentication.sh:
#!/bin/bash
# Asks for a username and password, then spits out the encoded value for
# use with authentication against SMTP servers.
echo -n "Email (shown): "
read email
echo -n "Password (hidden): "
read -s password
echo
TEXT="\0$email\0$password"
echo -ne $TEXT | base64
Make it executable and run it as follows:
chmod +x authentication.sh
./authentication.sh
When prompted, provide your e-mail address and password. This will look something like:
Email (shown): bob#gmail.com
Password (hidden):
AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==
Copy the last line (AGJ...==), as this will be used for authentication.
Notification
Save the following expect script as notify.sh (note the first line refers to the expect program):
#!/usr/bin/expect
set address "[lindex $argv 0]"
set subject "[lindex $argv 1]"
set ts_date "[lindex $argv 2]"
set ts_time "[lindex $argv 3]"
set timeout 10
spawn openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof
expect "220" {
send "EHLO localhost\n"
expect "250" {
send "AUTH PLAIN YOUR_AUTHENTICATION_CODE\n"
expect "235" {
send "MAIL FROM: <YOUR_EMAIL_ADDRESS>\n"
expect "250" {
send "RCPT TO: <$address>\n"
expect "250" {
send "DATA\n"
expect "354" {
send "Subject: $subject\n\n"
send "Email sent on $ts_date at $ts_time.\n"
send "\n.\n"
expect "250" {
send "quit\n"
}
}
}
}
}
}
}
Make the following changes:
Paste over YOUR_AUTHENTICATION_CODE with the authentication code generated by the authentication script.
Change YOUR_EMAIL_ADDRESS with the e-mail address used to generate the authentication code.
Save the file.
For example (note the angle brackets are retained for the e-mail address):
send "AUTH PLAIN AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==\n"
send "MAIL FROM: <bob#gmail.com>\n"
Lastly, make the notify script executable as follows:
chmod +x notify.sh
Send E-mail
Send an e-mail from the command line as follows:
./notify.sh recipient#domain.com "Command Line" "March 14" "15:52"
