Is there a way to block file attachments with certain extensions with Exchange 5.5?

There are several ways to do this. But all involve using 3rd party software. The type of software available is either AntiSpam software or AntiVirus software. Both of those should have this option.
I have been using Sybari AntiGen for Exchange and I never had a virus since.

With Sybari you can block based on the attachment also. They are releasing now a version that will also have Content filtering. Which means you can also block by subject line and/or message.

Are you looking to block internal -> internal attachments as well as external -> internal attachments?

If you're just looking to keep the bad stuff from coming into your network, you can also look at filtering at your SMTP gateway. If you don't have one, Symantec makes a nice one called "Mail Gear" that should do the trick!
