Scott, We, too, have medical clients who occasionally send legitimate ZIP files. After Ipswitch came out with the ability to STRIP or REPLACE attachments, we decided to block all binary attachments except ZIP files by replacing the files with text. Within a week, we had experienced more than 1,500 self-extracting ZIP files that were noting more than viruses attempting to propagate themselves via e-mail.
Upon experiencing that kind of attack, we added the ZIP files to the to the replacement utility and, within 1 week, had stripped more than 7,000 infected ZIP files from incoming messages. We sent a broadcast message out to all of our customers and not one of them had a problem. Most had previously been the recipient of an infected ZIP file (caught by an anti-virus program in every case). Not one complained. Given the current climate of viruses and hackers, we'll continue to block all binary attachments for the foreseeable future, including ZIP files.
