    Hi there,
    I'm setting up an email server using ISPConfig for the first time. I followed this guide to set it up https://www.howtoforge.com/tutorial...8-4-jessie-apache-bind-dovecot-ispconfig-3-1/
    Using Debian 8, Apache, ISPConfig 3.
    Emails can be sent but not received at the moment.

    Here is the error from /var/log/mail.logs
    Code:

    And the output from the ISPConfig test for common problems in the sticky thread.

    Can you send the /etc/postfix/master.cf as well.
    Are you using Dovecot or Courier. If you followed that tutorial to the letter you should be using Dovecot. The log file is way different than mine. I will show you an example of a successful delivery.

    Code:
    Jun 14 13:59:32 mail postfix/pipe[19929]: 18B31800A1: to=<user@domain.com>, relay=dovecot, delay=0.21, delays=0.05/0/0/0.16, dsn=2.0.0, status=sent (delivered via dovecot service)
    Notice how it is sent via postfix/pipe instead of postfix/local and it is also sent via relay=dovecot where yours is relay=local

    I fear you skipped a step.

    Please do not use these verbatim as it is heavily modified and most likely would not work straight for you.

    Hey,

    Thanks for the reply. The relay issue is as far as I got in trying to fix it. I couldn't figure out how to change the relay from 'local'.
    Yeah I'm using Dovecot. Here's my main.cf looks to me that maybe I haven't uncommented a few lines that I should have when comparing it to yours, maybe?

    Change:

    myorigin = mydomain.com

    to

    myorigin = mail.mydomain.com

    and restart postfix.

    You created domain.com in ISPConfig as mail domain and then you added a mailbox test.domain.com in ISPConfig?
    And domain.com is nowhere listed in postfix main.cf anymore and also not in /etc/mailname?

    TolhurstTech New Member

    Created email domain mydomain.com with server mail.mydomain.com and a new mailbox test@mydomain.com in ISPConfig.
    Main.cf is as above but with the edit you asked of me and /etc/mailname contains only mail.mydomain.com

    You listed mydomain.com in mydestination line, remove it there. As I wrote above, mydomain.com may not be listed anywhere in main.cf.
