Mail isn't sending or forwarding anymore

    I keep getting errors in my postfix log like:
    status=deferred (mail transport unavailable)
    Code:
    Mar 30 01:05:37 codyswartz postfix/error[10561]: 42F62429EC: to=<[email protected]>, relay=none, delay=1656, delays=1656/0/0/0, dsn=4.3.0, status=deferred (mail transport unavailable)
    
    I recently updated ISP config to 3.0.5.4p8 but haven't updated to the latest: 3.0.5.4p9
    I think this is when the problem first started showing up. When I send mail or mail hits the route I don't get any errors back in my mail client which seems odd.

    Please post the postfix main.cf and master.cf config files.

    Did you disable amavis befor or after this issue happened? When you disable amavis, then all mails that are still in queue for delivery will fail with a transport issue as postfix cant find the amavis transport anymore.

    The issue can also happen when you added transports in ispconfig and this transport endpoint that you specified does not exist.

    I had amavis disabled before this issue happened which I followed the guide for doing it properly as well.

    What do you mean by transports? The weird part is that the only thing I did was update ISPConfig and some software the day that this seems to have happened. I didn't touch any config files myself or change anything in the ISPConfig panel.

    I've just posted a new thread that sounds quite similar... maybe that CTS_AE got a problem like mine?

    Did you customize some of the amavis configuration files? In my case /etc/amavis/conf.d/50-user got overwritten exactly at the time of the upgrade of ISPConfig. Two lines added by me after install of ISPConfig were missing. Once I re-added the two missing lines in 50-user, restarted amavisd and postfix, mail queue started again to be processed, now everything runs well.

    If you can retrieve a working configuration of /etc/amavis/conf.d/ files probably you can restore missing parts.

    Kind regards
    Aldo

    I disabling these two lines did it, although I've been doing so much I'm not sure if this is what fixed it?

    /etc/amavis/conf.d/50-user
    Code:
    [email protected]_virus_checks_maps = (
    #   \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);
    
    via something here?: https://www.howtoforge.com/community/threads/disable-and-remove-clamav.44443/

    Can I just uninstall amavis if I'm not using it for anything?

    edit: it seems the forwards in ispconfig are not going through but everything else is now : ) & : (
    edit2: it seems to be saying "status=bounced (user unknown)"
    as if the items in the ispconfig forwards aren't being populated?
    Does an email mailbox have to exist before you can use a forward? I thought you could use a basic forward w/o having the overhead of a mailbox?

    When you update ispconfig and tell it to reconfigure services, it will reenable amavis again. You can see your commented settings in main.cf above:
    But just a few lines below that, those same settings are added again. You will need to create a custom-conf file with those disabled for that change to persist through ispconfig updates.

    You could probably add your 2 lines to another filename, eg. 99-local, and they won't get overwritten again.

    Ran into this again with the 3.1 update.
    I commented the lines out again, tried to run postqueue -f but the emails weren't processing; I believe they were retrying the amavis route. Running postsuper -r ALL processed them all :)
    One helpful command while doing this is postqueue -p to display the queue although you can see it in the monitor section of ISPConfig.
