Bypassing mail attachment blocking filters
This is mainly done for security reasons. In the past few years, the network admins have learnt that viruses and/or spammers trick the users into clicking on executable stuff in the mail and then take advantage of buffer overflow exploits.
So what do you do if you really really want to send someone an exectuable attachment? If you use PGP, GPG, or S/MIME to encrypt your mail before sending it out, then it would sail right past the mail attachment blocking filters.
ps: If you want a free personal digital certificate to use S/MIME, check this out from Thwate: http://www.thawte.com/html/COMMUNITY/personal/index.html
