Discussion:
question regarding email forwarding

Guys, I have to confess - the rules for SMTP_SERVER_REJECT. have
always confused me, so I need a little help. Here's the situation:

I'm hosting a domain (let's call it thedomain.com) for web service
that has an MX record that points to another server (at
mail.thedomain.com). As many of you are probably aware, there are a
number of clueless email clients that ignore the MX entry in the DNS
and attempt to deliver email to the IP in the A record.

What I'd like to do is write a rule to forward all email for
thedomain.com to their box at mail.thedomain.com . I *think* it
should look like this:

* * *thedomain.com n mail.thedomain.com

But I'm not sure. Would this be correct?

Thanks again,

I would say in this day and age, if the remote mail server cannot
process the MX record, ignore them :-) (many viruses that self-propagate
by SMTP ignore MX records, BTW)

We have dedicated boxes doing spam and virus filtering, and thus have
a number of MX records re-directing mail to those servers. The actual
mail server where the mail finally gets delivered has a filter that
only lets the mail scanner connect to it, thus forcing everybody to
use the MX pointer or their mail will not get through.

Sorry I can't help with the syntax of the rule ...

Verne, I couldn't agree more. Unfortunately, I really need to get these
emails from bouncing off my machine and directed to where they really
need to go - even if they're spam.

I tried the syntax that I had in my rejects file and it didn't work.
Is there a whiz at this sort of logic that knows the answer?

Thanks again,
