I am using the following command to login to my IMAP server:
openssl s_client -crlf -connect imap.server.com:993
After typing this command in the terminal I get:
* OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN] Server ready proxy1.mail.abc123.def456.com
...and from this point on, no matter what I type, the server rejects it.
C: SELECT INBOX
S: SELECT BAD CR sent without LF
I am having the hardest time finding a place online that will teach me how to take an email I have just sent with SMTP, login to IMAP and simply copy this sent email to the IMAP Sent folder.
Where online can I find this information? For SMTP, the information is all over the internet. For IMAP not so much as I keep getting search results about how to do it on Microsoft Outlook???!!
There are bits and pieces here on the site but no concrete functional examples I was able to find.
A bump in the right direction would be greatly appreciated.

I am trying to set up the most simple email server on an Amazon Linux 2 host for simple outbound mail (e.g. sending system messages). Following instructions on the net, I have installed mailx and sendmail. I am not committed to either package, I just want a simple setup with a minimal footprint. I have no problem switching to postfix if that is a better solution.
For configuration I have made the following changes.
/etc/sysconfig/sendmail:
DAEMON=no
/etc/mail/submit.cf (hostname obfuscated):
D{MTAHost}smtp.******.com
This works fine, and I am able to receive mail that is sent from the system.
There is a wrinkle. The anacron process is sending mail to the root account. However, rather than the mail being kept internal to the system it is being sent to the SMTP server. The SMTP server sends the message back to my host, which doesn't accept mail, and a loop is created when an 'undeliverable' message is send back to root on the host that doesn't accept mail.
How can I configure my system so email to root stays local and is not sent to the SMTP server? Any other 'best practices' suggestions would be welcome as well. And again, if switching to postfix is better, I am willing to do so (but will need configuration guidance).
I'm working on a Laravel 4.2 application that needs to be able to send emails. When the SwiftMailer component contacts the Microsoft Exchange server we use here it's receiving the following reply:
* OK The Microsoft Exchange IMAP4 service is ready.
* BYE Connection is closed. 13
My understanding is that I should be seeing SMTP response codes 220 and 221 instead of those asterisks; the SwiftMailer module is throwing an Exception when it receives the message without the codes.
I'm trying to do some investigation before bugging my coworker who manages the server in question. Does anybody have an idea how this substitution of asterisks for the codes may be occurring? I'm confident based on reviewing the code in SwiftMailer than this isn't occurring to the text of the response after it's received. Is this some sort of Exchange server security feature I'm unfamiliar with (and can't imagine the value of)?
The messages indicate that you are talking to an IMAP server, not an SMTP server. I'm guessing you put the wrong port number somewhere.
Odds are that you've got an "intelligent" network device between you and the server that's doing traffic inspection. I've seen this with Cisco devices, where the SMTP connection banner is replaced with a string of asterisks and all the command words in the SMTP traffic are replaced with "XXXX".
Hi i want to send mail via microsoft cmd console. I tried many way, but i didnt succeed.
i tried this article http://jpsoft.com/help/index.htm?sendmail.htm
sendmail "bob#bob.com bcc:joe#joe.com" Test Hello!
the error is :
'sendmail' is not recognized as an internal or external command operable program or batch file
and
this article : http://www.brighthub.com/office/collaboration/articles/21840.aspx#imgn_1
c:\>"c:\program files\microsoft office\office12\outlook.exe" /c ipm.note /m someone#gmail.com /a "c:\logs\logfile.txt"
the error is :
the process can not access the file because it is being used by another proccess
but it didnt worked. i dont know where is the problem or what is the problem.
thanks for your advice.
Scenario:
Your domain: mydomain.com
Domain you wish to send to: theirdomain.com
1. Determine the mail server you're sending to.
Open a CMD prompt
Type
NSLOOKUP
set q=mx
theirdomain.com
Response:
Non-authoritative answer:
theirdomain.com MX preference = 50, mail exchanger = mail.theirdomain.com
Nslookup_big
EDIT
Be sure to type exit to terminate NSLOOKUP.
2. Connect to their mail server
SMTP communicates over port 25. We will now try to use TELNET to connect to their mail server "mail.theirdomain.com"
Open a CMD prompt
TELNET MAIL.THEIRDOMAIN.COM 25
You should see something like this as a response:
220 mx.google.com ESMTP 6si6253627yxg.6
Be aware that different servers will come up with different greetings but you should get SOMETHING. If nothing comes up at this point there are 2 possible problems. Port 25 is being blocked at your firewall, or their server is not responding. Try a different domain, if that works then it's not you.
3. Send an Email
Now, use simple SMTP commands to send a test email. This is very important, you CANNOT use the backspace key, it will work onscreen but not be interpreted correctly. You have to type these commands perfectly.
ehlo mydomain.com
mail from:<martin9700#mydomain.com>
rcpt to:<recipient#theirdomain.com>
data
This is a test, please do not respond
.
quit
So, what does that all mean?
EHLO - introduce yourself to the mail server HELO can also be used but EHLO tells the server to use the extended command set (not that we're using that).
MAIL FROM - who's sending the email. Make sure to place this is the greater than/less than brackets as many email servers will require this (Postini).
RCPT TO - who you're sending it to. Again you need to use the brackets. See Step #4 on how to test relaying mail!
DATA - tells the SMTP server that what follows is the body of your email. Make sure to hit "Enter" at the end.
. - the period alone on the line tells the SMTP server you're all done with the data portion and it's clear to send the email.
quit - exits the TELNET session.
4. Test SMTP relay
Testing SMTP relay is very easy, and simply requires a small change to the above commands. See below:
ehlo mydomain.com
mail from:<martin9700#mydomain.com>
rcpt to:<recipient#someotherdomain.com>
data
This is a test, please do not respond
.
quit
See the difference? On the RCPT TO line, we're sending to a domain that is not controlled by the SMTP server we're sending to. You will get an immediate error is SMTP relay is turned off. If you're able to continue and send an email, then relay is allowed by that server.
Unless you want to talk to an SMTP server directly via telnet you'd use commandline mailers like blat:
blat -to you#example.com -f me#example.net -s "mail subject" ^
-server smtp.example.net -body "message text"
or bmail:
bmail -s smtp.example.net -t you#example.com -f me#example.net -h ^
-a "mail subject" -b "message text"
You could also write your own mailer in VBScript or PowerShell.
From Linux you can use 'swaks' which is available as an official packages on many distros including Debian/Ubuntu and Redhat/CentOS on EPEL:
swaks -f you#example.net -t someone#example.com \
--server mail.example.com
A couple more command-line mailer programs:
mailsend
Mail Alert Simple Mailer
Both support SSL too.
I found this article which explains sending email from telnet
http://www.kongtechnology.com/2008/01/27/smtp-authentication-and-send-emails-using-telnet/
but actually I have problem with it.
when i wrote this command
auth login
I got
Connection to host lost.
so, what is the problem?
http://www.ionfish.org/mxlookup
Type the URL of the site you want to find's mail server.
Open CMD, type:
telnet mx.sitedomain.com 25
then
HELO mx.sitedomain.com
next
MAIL FROM: president#whitehouse.gov
then
RCPT TO: secretary#whitehouse.gov
finally
SUBJECT: This message was brought to you in part by the moon.
Note: You need to send authentication requests, because most mail servers do not allow anonymous unsolicited mail to be sent. (spam).

I have a computer at home which I can't access from work. I'd like to be able to view results from work that my home computer produces. The best idea I've come up with is an automated script running on my home computer that emails myself the results (from a text file or stderr/out) when complete.
I'm decent with bash (I have a linux machine) and java, so an answer using either or both of those would be ideal, but if there's something easier that's fine too.
I typically use gmail, but also have yahoo mail.
My question is this: what would be the basic steps in solving this problem? I can do the nitty gritty stuff, but can't really get the big picture of how something like this would work.
Please help.

Howto set up ssmtp to send through a Gmail account
Some of the steps here might seem strange at first, but the rationale is put
in footnotes that should hopefully explain why.
First create a spare account on gmail which you will only use for
sending email. For instance, if your normal account is user#gmail.com,
create an account user.noreply#gmail.com with a newly created password
which you only will use for this account [1].
Set up the new account to forward all email to the normal account [2]
and under account settings you should add all other email adresses you
use [3].
Then install ssmtp (On Debian: aptitude install ssmtp) and edit ssmtp's configuration file /etc/ssmtp/ssmtp.conf:
root=user#gmail.com
mailhub=smtp.gmail.com:587
UseSTARTTLS=YES
AuthUser=user.noreply
AuthPass=passwdusedonlyforthisaccount
FromLineOverride=YES
and configure the local mail delivery by editing /etc/ssmtp/revaliases
assuming that your local login is localuser:
root:user#gmail.com:smtp.gmail.com:587
localuser:user#gmail.com:smtp.gmail.com:587
Make sure the two configuration files are readable to all users who
should be able to send email [4].
Test the setup by e.g. mailx (On Debian: aptitude install bsd-mailx):
echo 'testing, one, two' | mailx -s 'test 1' user#gmail.com
Hope this helps.
[1] The new gmail user name and password will be visible to everyone who
can log onto your machine, so you do not want this account to be
critical in any way, meaning you can close it down immediately if
someone should get access to it.
[2] If some email you sent bounces back to you, you might want to know
about it, and there actually exists people who will happily reply to an
email from johnsmith.noreply.
[3] Gmail will rewrite the From header on the email if it does not recognise the address.
[4] Ssmtp runs as the local user who sends the email, so that user needs
read access to the configuration files.
On any Linux I have used the mail sending from command-line is simple:
mail -s "My subject here" recipient#wherever.com <message_body.txt
AFAIK this acts as a front-end to sendmail, and you have to have sendmail configured to forward the messages to your ISP mail server.
You can't access your home computer from work which rules out a "remote support" option.
Can you access other computers on the Internet? If so, you could simply set up one of the online storage options and then ftp the results from your home computer. That's a lot simpler then trying to write scripts or code to generate emails with attachments or whatever.
You could then view the external computer from work.
If you have netcat, this command will send you an e-mail:
Given a file in this format (from Wikipedia):
HELO relay.example.org
MAIL FROM:<bob#example.org>
RCPT TO:<alice#example.com>
RCPT TO:<theboss#example.com>
DATA
From: "Bob Example" <bob#example.org>
To: Alice Example <alice#example.com>
Cc: theboss#example.com
Date: Tue, 15 Jan 2008 16:02:43 -0500
Subject: Test message
Hello Alice.
This is a test message with 5 headers and 4 lines in the body.
Your friend,
Bob
.
QUIT
Then netcat it to an SMTP server you have access to:
nc mail.somewhere.com 25 < file.txt
This will then send the e-mail. You can see how you can create a Java program to do this for you (just execute the commands).
Traditionaly, with unix systems like Linux, you'd have an MTA, a mail transfer agent, on the computer that deals with sending e-mail.
This could be a full blown e-mail server like exim, or something simple like ssmtp that just sends messages on to a relaying SMTP server such as would be provided by your ISP.
This isn't neccessarily the case anymore, since mail clients like Thunderbird include their own MTA, much like mail clients on Windows do.
However, it is likely that your distro will install some MTA or other by default, if for no other reason than the fact that other things on your system, like cron, want to be able to send e-mail. Generally there will be a command line tool called sendmail (sendmail being the original MTA [citation needed], other MTAs maintain compatability with its interface and it has sort of become the standard) that can be used from a shell script to send an e-mail.
My solution assumes that you have a SMTP server available which allows you to send an email programmatically. Alternatively, you can use a local install of sendmail which generally is available with most linux distros.
Create a standalone java program which watches the directory your home computer saves the file to. Use the JavaMail API to attach and send the file to any email you wish.
If you're also familiar with the Spring Framework, it has a nice abstraction layer for working with JavaMail and makes this sort of thing trivial.
Of course, your home ISP probably has the common SMTP port blocked as well.
