Question: Does anyone make the IIS SMTP service co-exist with IMail 6 ?
Details : We are a web design and hosting company running about 30 domains
on our NT
server (IIS 4/NT 4.0/SP 6a) and have 15 unique IP addresses.
One of our clients want to use IIS SMTP to send email using CDONTs so we
have enabled it and it is running. We have dedicated one IP address to IIS
SMTP .We have designated the client's domain as the default domain for IIS
SMTP. But we are also running IMail 6.0 as our primary mail server with
SMTP/POP3 for all the other domains. Imail is not set up to receive mail
for the client's domain and the IP used in IIS/SMTP is not used by any of
the virtual hosts in Imail.
We are able to use IIS SMTP to send mail but none of the mail from outside
is reaching the IIS SMTP drop box.
In IIS SMTP we have set the incoming port to 26 and the outgoing port to
25. Setting the incoming port to 25 causes the SMTP service to fail to
start - since I assume it is in conflict with IMail's SMTP Service. (Even
though I dont understand why the outgoing port on 25 does not cause a
problem and we are able to send mail on that port !)
It appears that Imail listens on all port 25 for all IP addresses not just
the ones assigned to virtual hosts. Is this correct ?
Does anyone have a solution for this - ie making IIS SMTP co-exisit with
IMail server so that it can process incoming mail for specified domains ?
Thanks
Arun
