ZappoScreech

Tired of having your e-mail attachments blocked by mindless and intrusive mail-server snoopware? Then download ZappoScreech and take back the freedom to send and receive any type of e-mail attachment. ZappoScreech is a small application that will quickly convert any kind of file, with an extension of up to eight characters, to a legitimate bitmap for attachment to an e-mail. Upon receipt of the e-mail with its attached bitmap, ZappoScreech will process the bitmap and recover the original file.

ZappoScreech contains no spyware or advertisements, and best of all -- is completely free.
