I have a domain server set up, and all incoming e-mails goes through anti-spam, anti-virus software before landing in my inbox.
This program shows history of all incoming e-mails. However, messages from mail-daemon (ie: delivery fail notifications) gets bypassed, and is not listed in the anti-spam software as an incoming email.
They go straight to my inbox without getting quarantined.
Does anyone know why this is so? Are mail-daemon messages designed to go straight into inbox? if so, how?
Sincerely,
Andrew
