Hooking POP3 Service of Windows Server 2003

Hi,
This port may look like an Unusual post in this Newsgroup .... but sorry I
don't know which is the best place to put this.

I have a requirement, in which we have to send email messages to a POP3
server. This is a Windows Server 2003 computer, running the POP3 service.
This will reject mails, if the receipant's name is Invalid. We have
requirements in which we have to look for a specific receipant's name in the
incoming POP3 mails and protect these mails from rejecting by Windows Server
2003.

Do we have any such API or Any other way, by which we can hook (or better do
anything that can tell POP3 service to not to Reject specific messages with
Invalid receipant Names). The limitation is that, We can't create a username
with the receipant name.

Thanks ....

Are you sure that it is the POP3 server that is rejecting the emails? I
would say that it is the SMTP server, because that is the one receiving
emails. All the POP3 server do is 'pop' the emails out to the clients.

The SMTP service has an excellent API. Just look up SMTP in the MSDN
documentation, and you will find alot of information.

Thank you for the Reply.

The Basic question from myself is that:
Can we stop rejection of mail (that was intended for such a user, which
does not exist at the Server) ?
If yes, how ?

Thanks Again.

Hello,

Alex Feinman wrote a "catch-all" script, that collected everything that was
_not_ sent to a valid recipient. You can find it here:
http://isorecorder.alexfeinman.com/catchall.htm

That maybe helps you do what you want to do?
(I'm sorry, SMTP scripting is not really my area of expertise)
