We have a E-smith 4.1.2 box that handles all our internal and external email. I collects our external mail from a POP3 server.
Over the weekend we seemed to stop receiving emails. I checked with the POP3 provider and the server has collected the messages as it is suppost to. Upon digging further I found all the messages in var/spool/smtpd/spool folder.
What seems to be happening is SMTPD is collecting the messages OK, but whatever is next in the mail delivery process is not correctly getting the messages and delivering them to the required users.
Has anyone seen this before or know what could be happening ??
I am also running RAV anti-virus, and restarted the server just before we started having these problems.....
