Also you seem to be triggering maildir scans which are expensive.

You should probably update your system to centos7 which at least has 2.2.10, which is still rather old, but less so. > > Warning: Maildir /var/spool/pop/domains/domain.it/username/Maildir: > Synchronization took 103 seconds (0 new msgs, 0 flag change attempts, 0 > expunge attempts) > > I wondering if there is something to try, at configuration level, to > "mitigate" this.. > > I use Maildir format, MTA is postfix, I have many users (> 10000) with > pop3/imap/webmail access.
