hi,
after i added a new isp interface, we cant access our mail server every 30 mins.
i only changed and add some rules from the outbound settings and the problem happened.
Nowhere close to enough detail here to even hazard a guess.

DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!
