Hello....
Qmail can be as a front end server. Firewall will do some
port forwarding to qmail... after scanning, qmail will forward emails to
Exchange.
What I've done is as below:
1) Install Qmail packages, make sure every packages are
properly installed.
2) modify
/var/qmail/control/rcpthost to allow your domain
to comes in
3) Allow relaying from your Exchange Server ( Users send
mails to Exchange, Exchange forward to Qmail then deliver to the
World)
- edit /etc/tcprules.d/tcp.smtp, add a
line like [exchange ip]:allow,RELAYCLIENT=""
then run qmailctl cdb to reload
4) When Qmail receive all email for scanning, you must
forward the mails to Exchange
- edit
/var/qmail/control/smtproutes add in your Exchange IP
and port eg: [exchangeip:25]
** Please don't add any virtual domain with vqadmin.
Don't add any domains & alias domains.
In Exchange, forward your DNS to your qmail box, then
every email will be forward to qmail for scanning, then qmail will deliver to
the world.
Don't forget to forward all incoming mails from port 25
in firewall to qmail box.
For more easier, you may use Webmin to configure Qmail in
GUI www.webmin.com
That's all about the config. Let us know the
result.
You can see through /var/log/qmail/smtp/current &
/var/log/qmail/send/current or /var/log/maillog
