A few days ago, my datacenter had to perform emergency maintenance. As a result, my Zimbra had to be migrated to a different host. After the migration, the Zimbra Amavis service was not running.
After checking the log, I found this information/error

You can highlight this information
Can't connect to TCP port 10024 on ::1 [Cannot assign requested address]
To solve this issue, you have two options.
Option 1
Please ensure that there is a localhost entry for IPv6 in the /etc/hosts file. If it’s not present, you can add the following line:
::1 localhost ip6-localhost ip6-loopback
Option 2
If option 1 fails, please do this.
Open amavisd.conf.in file
su - zimbra vi /opt/zimbra/conf/amavisd.conf.in
Add this line after “use strict;” (first line)
$inet_socket_bind = '127.0.0.1';
Save and start Zimbra service
zmcontrol start
Good Luck 🙂
