Hello everybody,<br><br>
this is exactly how we have our set-up - should we write some documentation and <br>
try to get it added to the MailScanner docs on the web site?<br><br>
- It's actually more DNS and PostFix/Sendmail set-up issue than MailScanner but <br>
I always thought that the MailScanner site would be a good place to centralise <br>
this information because it's going to be a "standard" requirement.<br><br>
Here's the concept:<br><br>
The domain is "mydomain.tld" and this IP_Addr is running a web and e-mail server <br>
(etc.,etc., etc.)<br><br>
We want to set up a separate host to act as a mail "hub" with MailScanner (spam <br>
and virus) which scans the mail before passing it onto "mydomain.tld".<br><br>
For the purposes of this exercise let's call this "mailscanner hub" host :<br>
"mailscanner.anotherdomain.tld"<br><br>
So,<br>
In order that mail for mydomain.tld is first sent to <br>
"mailscanner.anotherdomain.tld" we have to have access to the DNS - MX records <br>
for "mydomain,tld"<br>
We set-up two MX records:<br>
mydomain.tld MX10 mailscanner.anotherdomain.tld.<br>
mydomain.tld MX20 mydomain.tld.<br><br>
This makes sure that if there's a problem with our "mailscanner hub" mail still <br>
gets through....<br><br>
Don't forget that anotherdomain.tld is also going to accept e-mail via it's own <br>
MX records AND that mailscanner.anotherdomain.tld should be pointed to by an <br>
A-record and should NOT be a CNAME.<br><br>
Now, on mailscanner.anotherdomain.tld<br>
- we set up the mail server (my experience is with Sendmail and Postfix)<br>
- we set up Mailscanner<br>
and we test that it all works for mail going to anotherdomain.tld<br><br>
Then we set up Sendmail or Postfix to forward non-local mail to "mydomain.tld"<br><br>
From experience, the problem with this concept is the spammers who ignore the <br>
dns and send directly to the smtp server at "domain.tld".<br>
And, this is where someone else could help out with a good solution that doesn't <br>
mean installing another mailscanner on "domain.tld"<br><br>
Does this sound about right?<br><br>

PS: there are a couple of other tools needed of course - maildrop and MailWatch<br><br><br><br>
