iis smtp nntp: I have a W2k3 server that has several public ip addresses.
I want to -

A - Have each separate domain identify itself as mail.domain.com
B - Allow each domain to have the postmaster@domain.com account
C - Have ndr's list postmaster@domain.com
D - Allow pop3 access to all domains.

I know how to setup separate smtp virtual servers to accomplish A & C.
But I can't figure out how to allow pop3 access to these additional smtp
virtual servers. And when you setup postmaster@domaina.com, I don't
think it will still allow me to setup postmaster@domainb.com because it
still depends on a windows account.

Can smtp/pop3 within iis handle what I am trying to do?
Or should I be looking at a third party solution?

Thanks,

That's actually more of a DNS issue, but sure.

Each POP domain can have all the accounts you want.

That's a function of the SMTP server. In the properties for the
virtual server, set the account you wish NDR's sent to.

Sure. That's what POP domains are for.

I'm not sure what the problem is here. Your DNS defines the domains,
the MX records for the domain define the server IP, and the POP
mailbox is a fully qualified account name, so as long as the domain is
differnet you can have as many "postmaster" accounts as you wish. You
do need to be using AD for this to work, standard Windows accounts
don't understand multiple domains.

I don't see why not.

Third party solutions have advantages, which may be important to you.
I wouldn't rule them out if they make your life easier. Might look at
Mercury mail, a free mail server.
