Is it possible pass SMTP banner tests on any domains which are not also the default domain?

Post by luket » Sun Jan 31, 2016 8:58 pm

I run MailEnable with multiple domains and only one of them (the default domain) passes SMTP Banner Check over at mxtoolbox.com

I have read all the posts I could find here and over at Plesk, and it seems that it's simply not possible - or I have somehow missed the answer. So I simply wanted to ask the question outright.

Is it possible pass SMTP banner tests on any domains which are not also the default domain?

------------- configuration -------------

tamke.net (also default domain in ME)
Reverse DNS: 64.15.158.10 Points To mail.tamke.net
MX: @ MX 1h 10 mail.tamke.net
use mxtoolbox.com to Test Email Server, results: SMTP Banner Check OK - Reverse DNS matches SMTP Banner

game-master.net
Reverse DNS: 174.142.174.246 Points To mail.game-master.net
MX: @ MX 1h 10 mail.game-master.net
use mxtoolbox.com to Test Email Server, results: SMTP Banner Check - Reverse DNS does not match SMTP Banner

uoangelisland.com
Reverse DNS: 174.142.174.242 Points To mail.uoangelisland.com
MX: @ MX 1h 10 mail.uoangelisland.com
use mxtoolbox.com to Test Email Server, results: SMTP Banner Check - Reverse DNS does not match SMTP Banner

------------- end configuration -------------

So as far as I can tell everything is perfect and MailEnable simply does not provide anything but the default domain in the SMTP Banner guaranteeing all but the default domain fail this test.

If I am right there, there should be a clear statement to this effect - a warning when configuring anything but the default domain.

Thoughts? Feedback? Workarounds?

Okay,

I've found a pretty good work around for the above stated problem.

I solved the problem by configuring one Windows Virtual SMTP server per domain/IP then Smart Hosting MailEnable to handle final delivery and other processing.

When email targets my game-master.net domain, it is first routed to a Windows Virtual SMTP server for that domain/IP.
When the remote SMTP server contacts my server, my Windows Virtual SMTP replies with:
220 game-master.net Microsoft ESMTP MAIL Service, Version: 7.5.7601.17514 ready at Wed, 3 Feb 2016 12:08:10 -0800 [656 ms]

This is good as my banner now matches my reverse DNS. I.e.,
SMTP Banner Check OK - Reverse DNS matches SMTP Banner

My Windows Virtual SMTP game-master.net then hands off the request to my Smart Host (MailEnable.)
This works great for all email, both in and out of my server.

But there is a problem with 'lists'
** LIST PROBLEM **

If I connect directly to ME without a smart host, LIST processing works as you would expect. But when I use the system described above, my email message sent to the list appears in the C:\inetpub\mailroot\Drop folder which is maintained by Windows Virtual SMTP, but I never see it hit my ME server.

I don't see any complaints on the virtual smtp side, and it never seems to even hit the ME server.

heh, and ideas?
