Delete Default SMTP in IIS

[Ron Hinds]

I finally gave up on using the POP3 server that comes with Windows Server
2003. Installed XMail, which seems to work beautifully and none of the
issues of the MS POP3. XMail is a SMTP server, too. so I disabled the IIS
SMTP service. I ran into a problem, though: We have several websites running
on that machine, some of which send eMail using CDONTS. CDONTS works by
placing messages directly into the Pickup folder of the default SMTP server.

XMail allows this and has a folder for it, but it requires the message to be
formatted a certain way and also named a certain way, none of which is
configurable by CDONTS. Rewriting the website code to use a different mail
method is not an option at this point. So, I restarted the IIS SMTP server
configured to use a port of 50505. I left the MS POP3 service disabled. My
problem is that any eMail sent to an internal domain gets routed to the old
POP3 mailboxes. I don't understand how this is possible without the MS POP3
server running, but there it is. So I figured if I remove all of those
domains from the default SMTP server, it would send to the XMail SMTP
server. But, I cannot delete any of the domains! Delete doesn't even appear
on the right-click menu, and pressing the Del key has no effect! So I
figured I would just delete the whole default virtual server and start over
(which is my top choice anyway), but that doesn't appear to be possible,
either. Any ideas?

Can you not re-enable the POP3 service and remove the domain(s) from it
so that IIS's SMTP service does not believe the domains are local?

I would also suggest re-configuring IIS's Default SMTP server to Smart
Host through XMail so you have one egress SMTP queue to worry with.

Yes, I have done the Smart Host already. It still distributes the mail to
those domains as though they were local though. I will try your first
suggestion and see if that cures it. Thank you!

I don't understand how this is possible without the MS POP3 server
running

Delivery to the mailbox directories is done by the SMTP service when
the POP3 event sinks are installed. The POP3 service only needs to be
running for retrieval over TCP 110. (This is quite the same
arrangement as most mail suites.)

Any ideas?

What Grant said. You should really just remove POP3SVC if you are
retiring it.

Thanks - I wasn't aware of that.

I will do that as soon as I try Grant's suggestion.
