I am trying to write a legitimate application for work but need to test it out.
The IT dept is crap at getting back at me so I gave it a go myself.

I have IIS installed including the SMTP server, but I still cant send any mail through my app.
Is it possible for my IT department to restrict SMTP mail?

I just want to connect to my SMTP server on my PC from my PC and send an email to myself (which will go via the Exchange server at work).
