Yes as I set mine this way. 

1.  Remove the Imail MX record from your DNS zone file.  I realize Symantec
says to make the mail server a lower priority MX, but then it leaves your
Imail mail server open to accpeting mail without it being scanned for
viruses first.  You only want to have one MX record at this point.  Yes, it
will remove your backup MX, but the laternative is to pass viruses to your
users.  There are also spamware/virus programs out there that will send mail
to any MX, not just your primary.

2.  Set your Imail server to no-mail relay.  Only add the allowed IP address
of the SAV SMTP gateway server IP.  This means any one can send mail to your
server as long as the recpient is legit.  *BUT* only peopl who use SMTP auth
will be able to use your SMTP service to send mail form your server.

3.  Make sure all users use SMTP auth in their client.

4.  Realize that this will remove any DNS blacklists test validity from
Imail as Imail will always see the SAVSMTP server as the sending server.
This is ok.  Configure SAVSMTP to do the DNSBL scanning for you.  If you
have version 3.1.1 or higher (4.0 will be out next month I am told it may
support weighted testing and thrid party plugins as well as statistical
filtering.  These have all been on the drawing board for sometime.  It will
also support something similar to deculde where it will automatically send
virus notifications out only to those know to not disguise the sender) this
will be fine.

5.  Make sure you set SAV SMTP Gateway correctly or you will be an open
realy out of the box.

6.  If you are having any problems, I can set SAVSMTP up remotely as I have
done it for a few others here on the list as well.  Contact me off-list
tomorrow.

All of this should work unless I have missed something.  Someone else will
chime in if I am wrong.


Good Night,

Travis
