I've set up mail server with iRedMail. It should act as an SMTP server for web app. Postfix is restricted only for localhost usage.
Let's assume that I create an account web#example.com.
What I need is to allow set arbitrary from header, e.g. bar#example.com, or even baz#my-second-domain.com
Currently this is rejecting:
postfix/smtpd[7386]: NOQUEUE: reject: RCPT from ***[127.0.0.1]: 550 5.1.0 <notlviv#pb.org.ua>: Sender address rejected: User unknown in virtual mailbox table; from=<notlviv#pb.org.ua> to=<some#email.com> proto=ESMTP helo=<[127.0.0.1]>
How can this be allowed?
Ok, figured out:
smtpd_reject_unlisted_sender = yes # set to no
# Sender restrictions
smtpd_sender_restrictions =
reject_unknown_sender_domain
reject_non_fqdn_sender
reject_unlisted_sender # comment this

How do I send postfix bounce to another SMTP server?
I have 2 postfix server (server_A and server_B).
I need the bounce generated from server_A sent to Internet by server_B.
Half a year late... You should try adding this into your main.cf file located in your postfix directory:
notify_classes = bounce, 2bounce
bounce_notice_recipient = <server_B mail address>
2bounce_notice_recipient = <server_B mail address>
*Feel free to include other options in your notify_classes (eg. delay, policy, protocol, resource, software, data) if needed
Addition info: http://www.postfix.org/postconf.5.html#notify_classes
Postfix version 2.11.0
What I'm trying to accomplish is to have mail destined for a particular domain to be relayed through SendGrid but all other outgoing mail to be sent from my local server directly. I have this configuration in /etc/postfix/transport:
example.com smtp:[smtp.sendgrid.net]:587
.example.com smtp:[smtp.sendgrid.net]:587
* :
My understanding from all the searches I've done and reading the Postfix docs is that this should work but if I send to any other domain, for example gmail.com it's still getting relayed through SendGrid.
An example from /var/log/mail.log:
Oct 26 16:15:46 myhost postfix/smtp[25783]: A75F0C04F9: to=<PRIVACY_MASKED#gmail.com>, relay=smtp.sendgrid.net[108.168.190.108]:587, delay=11, delays=11/0.02/0.22/0.03, dsn=2.0.0, status=sent (250 Ok: queued as iTwf5zmCQQSgz_I6sVpSSA)
Is there some other configuration I'm missing?
Ok, now I see the error of my ways. In sasl_passwd I had this:
smtp.sendgrid.net USERNAME:PASSWD
But in transport I had this:
example.com smtp:[smtp.sendgrid.com]:587
The difference is .net versus .com.
Changed it to .net and works!
I recently installed Postfix, Dovecot to setup a mail server on my own VPS ( using this tutorial: Email with Postfix, Dovecot, Mysql)
Imaps server uses port 993 for Authentication, and Postfix uses port 25 to send mails.
In this tutorial, users stored in a Database ( so imaps use mysql to authenticate users).
i'm sure every thing works fine with imaps and postfix , because few days ago i installed Kmail client (on my linux) and receive mails from my server. sending mails also works fine, i sent a mail to Gmail and google received it without a problem (in my "Gmail inbox" not spam folder)
So to get to my Emails from a web mail client, i installed Roundcube on /var/www/mail directory.
I configured Roundcube many times. but each time it gives me this Error:
IMAP Error: Login failed for [me#mydomain] from X.x.X.x . Empty
startup greeting (localhost:993) in
/var/www/mm/program/lib/Roundcube/rcube_imap.php on line 184 (POST
/mm/?_task=login?_task=login&_action=login)
When i do log in from roundcube, imap server says ( in /var/log/mail.log ):
May 20 07:05:16 my-server dovecot: imap-login: Disconnected (no auth
attempts): rip=::1, lip=::1, TLS handshaking: Disconnected
Here is my roundcube config file :
$config['db_dsnw'] = 'mysql://roundcubeuser:myPassword#localhost/roundcubemail';
// ----------------------------------
// IMAP
// ----------------------------------
$config['debug_level'] = 13;
$config['default_host'] = 'ssl://127.0.0.1';
$config['default_port'] = 993;
// ----------------------------------
// SMTP
// ----------------------------------
$config['smtp_server'] = 'ssl://localhost';
What's the problem? i really have no idea what is happening !
Thank you.
I'm using postfix + dovecot + roundcube a few months now and it's working for me. In my configuration, postfix rejects plaintext sessions, so roundcube has to connect with ssl - and it's working.
This is from my main.inc.php. I don't remember editing anything here, it's just the initial config created during the installation.
Now that I'm looking at it, default_port doesn't make any sense, I think it's just ignored.
// To use SSL/TLS connection, enter hostname with prefix ssl:// or tls://
// Supported replacement variables:
// %n - http hostname ($_SERVER['SERVER_NAME'])
// %d - domain (http hostname without the first part)
// %s - domain name after the '#' from e-mail address provided at login screen
// For example %n = mail.domain.tld, %d = domain.tld
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 143;
$rcmail_config['default_host'] = array("ssl://localhost:993");
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 143;
In case the other answer does not work, this is what worked for me. My config.inc.php now contains:
$config['default_host'] = 'ssl://localhost';
$config['default_port'] = 993;
NOTE: using tls://localhost did not work for me. I had to specify ssl:// as the URI scheme.
Via PhpMyAdmin, I also ran this SQL command (all my user accounts are on the same machine that runs RoundCube):
UPDATE `rc_users` SET `mail_host`='ssl://localhost'
I got the port number 993 from running sudo netstat -tulnp in order to determine the port on which Dovecot was listening.
I'm using Grails Mail plugin and trying to send email and keep getting:
Error 500: Executing action [sendInvite] of controller
[RegisterController] caused exception: Failed messages:
javax.mail.SendFailedException: Invalid Addresses; nested exception
is: com.sun.mail.smtp.SMTPAddressFailedException: 550 must be
authenticated
I'm properly following the instructions at: http://www.grails.org/Mail+plugin
The mail server is returning an error when you try to send out the mail. 550 is a generic SMTP failure code; in this case it looks like you are missing a username and password. Some SMTP servers to not require authentication but most do, especially if they're publicly available on the internet. It's also possible that your SMTP server requires an SSL connection and you're connecting with an unsecured socket.
The example config for gmail shows how to set all the mail server authentication options in Config.groovy:
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "youracount#gmail.com"
password = "yourpassword"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
Add "mail.debug": "true" to props to turn on JavaMail debugging to get a better picture of what is happening before the failure.
In my case the 550 error was caused by me having accidentally selected and IMAP account as the default account but sending emails from my Outlook Connector Account (which has no authentication settings to make).
I changed the Outlook Connector Account to default. Resent the emails and no errors.
So check that the correct email account is set up as the default also
I'm using postfix to send email via gmail with an application's password (two step-validation activated).
Each time I test sending mail using sendmail command, I get this error:
Action: delayed
Status: 4.7.14
Diagnostic-Code: X-Postfix; delivery temporarily suspended: SASL authentication
failed; server smtp.gmail.com said: 534-5.7.14
<https://accounts.google.com/signin/continue?...> Please log in via your web browser and?534-5.7.14 then try again.?534-5.7.14
This is my postfix configuration:
main.cf
myorigin = /etc/mailname
mydestination = mydomain.com, localhost.fr, localhost
relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd
smtp_tls_security_level = encrypt
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
/etc/postfix/sasl/sasl_passwd:
[smtp.gmail.com]:587 admin#mydomain.com:application_password
And this is how I used sendmail:
sendmail -v ...
From: admin#mydomain.com
Subject: Test
This is a test mail
.
Any ideas ? Thanks !
