Hi,
I have a Plesk 11.x server with a couple of domains hosted on Debian Linux.
We use Postfix as MTA and have a couple of external ip-addresses setup on the server, some are dedicated and some are shared.
We use a.b.c.2 as a dedicated ip-address for DNS (ns1.domain.tld) and a.b.c.3 for mail (smtp.domain.tld).
But when users send mail from the webmail they are sent from the shared ip-addresses. And since we have no PTR records setup the shared ip-addresses some mails get trapped in spamfilters.
Is it possible to make webmail only send mail from a.b.c.3 address?
I tired changing /etc/postfix/master.cf to only use that address but that didn't work, I ended up with not being able to send emails at all.
And i had to restore the mail functionality.
Kind Regards
Magnus
