MailScanner and (FreeBSD and Plesk+Qmail)

[Alex Neuman]

This might be a bit off-topic, so I apologize in advance.

I have a friend who wants to use MailScanner + ClamAV + SA + Razor, and he
has a FreeBSD server that's being administered using Plesk, and his server
is using Qmail for e-mail. This is not changeable because of political
reasons, so we can't switch to postfix/sendmail/exim or whatever.

I've been meaning to help him out since I've installed
MailScanner+ClamAV+SA+Razor (along with other different configs) using Linux
for some time now, but I've never had the opportunity to get MS running on
FreeBSD.

It seems to me I've installed everything needed, and I have a plan of action
I'd like to show the group in order to get your feedback / comments:

1. Get another, secondary IP address
2. Configure sendmail to use that IP
3. Add server's domain to relay-domains and mailertable, pointing to main IP
address
4. Configure DNS's to make secondary IP address first MX, and main IP
address to second MX
5. Start MailScanner

My logic goes something like this:

1. Someone sends SMTP message to server
2. Asks DNS for MX
3. Gets first MX, so sendmail gets the message
4. MailScanner processes it
5. Second sendmail process sends it to main IP address
6. Qmail gets the message.

My reasoning is that if for any reason MailScanner isn't working, or the
sendmail processes break, mail will be received by the second MX (qmail) so
that service will not be interrupted.

Let me know what your opinions are. If this is way off-topic I apologize
again.
