Such low mail rate could be the reason for persistent LDAP sessions
to time out. The default is to use persistent SQL and LDAP sessions:
$database_sessions_persistent = 1; # keep SQL & LDAP sessions open when
idle
Starting with 2.8.0 this can be turned off:
$database_sessions_persistent = 0;
See also my work on Net::LDAP. The newest releases allow turning on
keepalive (default 2 hours). I also have a patch for it that, if you are
on linux, allows tweaking the keepalive parameters for the Net::LDAP
connection so that you can send keepalive probes much more often than those
2 hours.
In addition, I started a thread a while back about bugs in Amavis where it
does not properly handle certain error conditions with persistent
connections, causing it to not retry connections when it should. I believe
I supplied a recommended patch for that as well. ;)
