Hi!

Our co-lo runs a mailhub which pre-scans email for virus's and spam 
before passing it on to my server (where it is also scanned for spam 
and virus's)

I am told that many spammers try to skip the mailhub and send 
directly to the end servers.

Is it possible to configure my BQ box to only accept mail from the 
mailhub and reject everything else?

Would this cause problems for my users who use my servers to send 
mail using pop-before-smtp?

Would this cause problems for email generated on the server itself 
destined to mailboxes on itself? (ie: active monitor etc)

- Bill
