    Hello,
    I recently updated ISPconfig to the latest version and ever since I updated, I am not able to send or receive emails. Every time I attempt to send an email I receive this error message"Diagnostic-Code: X-Postfix; mail transport unavailable". I am running the latest version of ubuntu on a dedicated server.

    Thanks in advance,
    Ali

    Maybe you can show some lines from mail.log when you try to send a mail? And check, that amavis and dovecot are running.

    Here are some lines that might help from mail.log

    Code:
    
    2 20:56:30 server1 postfix/qmgr[20579]: A86B750C047F: from=<[email protected]>, size=1847, nrcpt=1 (queue active)
    Jul 22 20:56:30 server1 postfix/qmgr[20579]: warning: connect to transport private/amavis: No such file or directory
    Jul 22 20:56:30 server1 postfix/error[22636]: A86B750C047F: to=<[email protected]>, relay=none, delay=273631, delays=273631/0.01/0/0.05, dsn=4.3.0, status=deferred (mail transport unavailable)
    Jul 22 20:56:50 server1 dovecot: imap([email protected]): Connection closed in=43 out=875
    
    
    P.S I replaced the real domain with domain.com

    Both Dovecot and Amavis are running as well

    And what are the settings for the amavis-service in postfix master.cf? I use
    Code:
    amavis unix - - - - 10 smtp
        -o smtp_data_done_timeout=1200
        -o smtp_send_xforward_command=yes
        -o disable_dns_lookups=yes
    
    and content_filter = amavis:[127.0.0.1]:10024 in the main.cf

    The content_filter = amavis:[127.0.0.1]:10024 in the main.cf is commented out

    ISPconfig adds content_filter = amavis:[127.0.0.1]:10024 to the main.cf.
    smtp-amavis in your master.cf should be amavis.
    Did you run reconfigure services during the update?
     
  7. Aligator12

    Yes, twice.

    Should i try once more?
     
  8. florian030

    florian030 ISPConfig Developer ISPConfig Developer

    No. Which OS are you running? And can you post your master.cf an main.cf?

    Your configs are not from a normal ispconfig setup/update.
    In the main.cf use content_filter = smtp-amavis:[127.0.0.1]:10024
    In the master.cf change at least the flags for DOvecot to DROhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-deliver -f ${sender} -d ${user}@${nexthop}
    And make sure, that amavis listens on Port 10024 (netstat -tanp|grep 10024).

    I followed your instructions and then tried to send an email. The email was successfully sent, but unfortunately never received. I sent it to a gmail email

    Did you see any errors in the mail.log during the transfer to gmail? Have you check the spam-folder, too?

    I checked /var/log/mail.log and Found no error messages, and checked the spam folder

    IF the mail was sucessfull delivered to google, you should ask google.

    From time to time someone tries to connect to your server... Check for connects from gmail in your log. And make sure, that your port 25 is open an reachable from outside.

    Is the entry related to a mail before you changed the configs?
    See Post #10 - if you play around with the configs, you can break the mailflow. Is there any reasons why you changed the configs?
