Moved our MX to our new server. We were running on a Redhat 9 boxen, now
on Redhat AS 3.1. Fresh install of MS 4.40.11 and let her go. I started
getting funny calls from from my fellow employees about receiving funny
zip files. Being lazy I just talk with them on the phone and was able to
assist them with opening the zipped attachment using Outlook. Well we
sent our payroll files yesterday and the company receiving them refused
to work with them because both files had been changed from something.zip
to something.zip.zip. Wanted to get paid next Friday I decided to take
this seriously. This is what I saw in the maillog:

This was with clamavmodule, so I switched to clamav and then got this
error:

In both cases the files where delivered, but an extra '.zip' was added to
both files. So I upgraded to the latest stable and still get the same
