Hi folks,
I am a relative novice with Imail Server.
(More an Exchange guy) We inherited a number of Imail Servers when we
acquired another company recently.
We now have the
servers behind our Barracuda spam/virus firewall. We noticed that bogus
SMTP email addresses such as [EMAIL PROTECTED] or
[EMAIL PROTECTED] are coming
through. The Barracuda eventually learns that these are spam and stops
them. The messages are funneled into a particular user account for
each domain.
In Exchange, a
message with an incorrect SMTP address to one of my users would be accepted and
would immediately generate a non-delivery report (NDR) to the sender with an
SMTP status code that essentially said "bad destination mailbox address".
These messages would be funneled to an NDR mailbox for later review by an
administrator.
I would like to do
one of two things in order of preference:
Have Imail reject
all mail that is destined for a non-existent user. ie, Imail verifies
the SMTP address exists before accepting the message. (I'd call this
'SMTP Rejections' or something similar) (This is what Barracuda Networks
recommends) Have Imail send an NDR of some sort. Currently it does
not send an NDR.
OR
Change the mailbox
that accepts messages with incorrect/non-existent SMTP addresses (i.e. change
the NDR mailbox). Unfortunately these messages are currently going to an
admin or secretary for each domain who is being inundated with this junk. For
the life of me I can't figure out where this is configured for
each domain. Further turn on NDR's for incorrectly formatted
SMTP addresses so that senders would know the message did not reach their
intended recipient.
I'm guessing that
the first option won't be possible in my version of Imail, but option two is
probably beyond simple and I'm just missing it. If I can provide any
further information or clarification I'd be happy to.
Thanks
folks,
Mike
