I have setup a simple mail system using the Windows Server 2003 Integrated
SMTP/POP3 services. Everything is running smoothly, and am able to
successfully send/receive emails but for some reason I cannot send emails
with certain file type attachments such as .zip. I tested some random file
types also (such as .xy3) but am unable to send those as well.

I can send attachments with file types like .txt or .jpg, and I am able to
receive .zip files. I have been using both Outlook Express and Outlook 2003
to test send the .zip files, so I don't think its an Outlook problem, but I
could be wrong.

Any help or guidance is sincerely appreciated!! Thanks!
