Error: Postfix/amavisd - connect to[]:10024: Connection refused

You use a Postfix setup with amavisd-new and get the following errors in your mail log:

Aug 17 14:58:33 server1 postfix/smtp[5993]: F0C57124E77: to=<[email protected]>, relay=none, delay=2524, delays=2524/0.27/0/0, dsn=4.4.1, status=deferred (connect to[]:10024: Connection refused)


Aug 17 09:42:24 server1 postfix/error[7809]: 15D54124E53: to=<[email protected]>, relay=none, delay=269, delays=0.49/269/0/0.04, dsn=4.4.2, status=deferred (delivery temporarily suspended: conversation with[] timed out while receiving the initial server greeting)



Please restart both amavisd-new and Postfix and then check with

netstat -tap

that both are running on the ports

25 and 10025 (postfix)


10024 (amavisd-new).

Thank you very much for this. I was getting this issue because amavis wasn't actually running.

yes, starting the amavis was the solution...

What if the problem is repeating itself after about 5 days?
What causes these services to stop? Logging gives no clue (because there isn't any) 
I have to restart the mail server every now and then. It's a production system with lots of users. Very inconvenient.
System: Debian Wheezy

Did you get a solution for the postfix/amavis hangs? I got exactly the same Problem. Every few days i have to restart postfix and amavis...


Starting amavisd: hostname: Name or service not known
  The value of variable $myhostname is "", but should have been
  a fully qualified domain name; perhaps uname(3) did not provide such.
  You must explicitly assign a FQDN of this host to variable $myhostname
  in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's
  network name!

 When you receive this error make sure you edit your /etc/hosts file for your server like this (with your details):

[..]     server1

and /etc/hostname:

Hi Till,

I have the same here with fresh installation and following the instruction on Perfect server setup Ubuntu 20.04I did the install on Ubuntu 20.04 LTS and Debian 10, but ended with the same result. After ten or more times reinstalling I don't know where to search anymore. Maybe you know the answer, restarting Postfix and Amavis was not the solution for me.

Please post in the ISPConfig support forum if you need help with your ISPConfig installation:

A common mistake is that a wrong hostname is set on your server so that 'hostname -f' command on Linux fails to display the full (fqdn) hostname. In such a case, amavis will fail to start. Fix the hostname and start amavis then.
