Mail stuck in queue ( connect to 127.0.0.1[127.0.0.1]:10024: Connection refused )

Whenever I flush the postfix queue, I have a list of deferred messages with this in it:

postfix/error[11703]: 5342CC65B0C: to=x, orig_to=X, relay=none, delay=545560, delays=545560/0.22/0/0.01, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)

but this ISPConfig server runs rspamd, there is nothing listening on port 10024 (!?), there is no amavis on this server as far as I can see.

And, another (perhaps related) thing is that I was at first unable to even see the queue, or flush the queue, because the pickup line in master.cf was commented out! This is using debian 12 clean OS installed with postfix mail_version = 3.7.11 installed by ispconfig install, using the standard debian repos. Just sayin', seems to me that this pickup line in master.cf needs to be uncommented by ispconfig scripting, or you'll see many more users with this issue.. I'm not assuming that the official release of postfix carried by debian has this commented out, or whatever happened, but I found another thread in the forum with the exact same issue on debian 12.

Can someone post his/her master.cf from a debian bookworm ispconfig install with postfix and rspamd ?
I don't even remember if amavis was installed or not, I used this to install ispconfig quite long ago:

Code:

wget -O - https://get.ispconfig.org | sh -s -- --use-nginx --no-dns --use-unbound --use-php=7.4,8.2 --no-mailman --no-quota --no-ntp --no-firewall --no-quota --unattended-upgrades=autoclean

And this server's current master.cf:

Code:

# cat master.cf
#
# Postfix master process configuration file.  For details on the format
# of the file, see the master(5) manual page (command: "man 5 master" or
# on-line: http://www.postfix.org/master.5.html).
#
# Do not forget to execute "postfix reload" after editing this file.

Thanks in advance for any info on all this.
(Yes, I realize I can run a vm or free hoster instance to just try and clean install ispconfig the same way and then copy the master.cf from that, but I'm lazy and posting this seemed useful either way)..

 

On my Debian 12 installed from Debian installation media and ISPConfig installed with auto-installer the pickup line is not commented out.
That master.cf is 147 lines long, twice as long as what you posted. Most of the lines are comment lines, though.

 

Made a clean install this week on Debian 12 aswell. No such issues, everything works as expected and is configured correctly. Are you sure you just did a clean install and there was no configuration or packages installed beforehand?

Installed with:

Code:

 wget -O - https://get.ispconfig.org | sh -s -- --no-dns --no-pma --no-mailman --use-ftp-ports=40110-40210 --unattended-upgrade

 

Yes, I moved all commented stuff out of the master.cf for easy viewing. Since nobody is posting his/her master.cf I will try and find out on a clean debian 12 VM and see where it went wrong. Either way, the first issue, where deferred mail is *still* looking for port 10024 is not solved. I have never installed amavis on this debian, so whatever it is, ispconfig somehow tried amavis before it installed rspamd or something? I have also switched the content filters from rspamd to amavis, saved it, set it back and saved it again. To no avail. The deferred messages are still there. By the way, all in/out mail works fine aside from this, so it's probably an old bunch of messages, but still strange how there are so many of them (a list of about 24, with several valid existing to: addresses on this server).

 

Did you install ISPConfig on a fresh install of Debian 12 or was the host in use for something else before?

I don't think that that would be super helpful, as something went wrong and we should try to find out what happend instead of just copying over config that may not work on your system. Anyways you can find all config files in the ispconfig install archive which you can download on the website.

 

It was a minimal debian 12, so yes, I had to install openssh, and some minor tools, like mc and wget, but definitely no exim because I detest exim. ISPConfig has installed postfix for me, that's for sure.

No. There is no postfix master.cf that ispconfig uses, it only ads to the existing one.
