- Does it have the capability of notifying our ticketing system(ie emailing out a breech of quota email) if a user has consumed their quota?
Dovecot (IMAP/POP3 server) will execute a script when user mailbox quota reaches 85% full (or 90%, 95%), you can modify the script to mail to your ticket system. The script is defined in /etc/dovecot/dovecot.conf (on CentOS 6.x) in block "service quota-warning {}", default is /usr/local/bin/dovecot-quota-warning.sh.
