Re: Alternate ports on Outbound mail domains

In one of my tests, I had this setup with a single ip-address:
1) SMTP Virtual Server #1: Listening on port 25, delivering on port 25
2) SMTP Virtual Server #2: Listening on port 2525, delivering on port 2525
3) SMTP Connector #1 with SMTPVS1 : Address space = * (all domains) and cost
10
4) SMTP Connector #2 with SMTPVS2 : Address space = domain1.com and cost 1
I expected mails received on SMTPVS1 to be handed over to SMTPVS2 and
delivered on port 2525, but instead Exchange tried to deliver on port 25 and
returned the mail as undeliverable. Afterwards I configured both VS's in the
same SMTP Connector, but still the mail routing failed.

>From the test I conclude that SMTPSV1 can only pass mails to SMTPVS2 if
sending and listening ports match.
But I hope I am wrong???
