Hello,
I have been tasked to come up with a solution, but before I go into it, i
thought some background information
would be prudent:
Currently, we have about 1000 mail users.
Currently, we have two Microsoft Exchange Server 5.5/SP3 running. (names
mail1/mail2)
In front of Exchange is two Windows NT Server 4.0 Machines with Norton
Anti-virus (name av1/av2)
in front of the Anti-virus gateways we have a Cisco Local Director that
manages traffic
to the two anti virus gateways.
we also currently have a secondary qmail server on FreeBSD 4.1, which is
working quite well. It
just queues up messages until the primary comes back on-line. (name qmail2)
What we are now looking to do, is to replace the Norton Anti-Virus Machines,
with a new FreeBSD
Box. What we would like to do is install Qmail and the AVP virus software
package.
At somepoint, we are looking to have both Norton Anti-virus machines
replaced with Qmail/AVP.
One of our issues is, that we want email to come into the Qmail box, have
AVP check for virus', and
if it is clean, first we want to store each message into a User Mailbox, and
then forward it to Exchange
for ultimate delivery. The reason we want to do this, is that if for any
reason our exchange server
goes down, that it would be possibly via a pop client for a user to get
their email.
The issues that I am looking at,
Need a way to make sure accounts exist on both Exchange and Qmail
are synced somehow.
We are only wanting to keep email stored for a few weeks, maybe a
month at most. So some sort of purge/mail box trim with date
sensitivity is needed.
One thing I am now looking into, how does AVP fit into the Qmail Picture.
Currently, with
Norton Anti-virus, it works on port 25, and after passing the virus scan
sends it to Exchange.
There is no storage of messages here.
I am looking into AVP Today, and how it fits into the Qmail Picture. Their
website doesn't
have a lot of documentation, and i'll probably need to download a copy to
see if there is any
further info on it.
The Big question is, how do I get it to store a message in a users mailbox,
and then forward it.
I am looking at qmails forwarding options, and i believe that i will have
to forward it specifically to mail1.lifetimefitness.
What impact will this have on the message itself, header, etc.
Looking for anyones experience in this area
