That is the exact issue I am seeing (even to the clamassassin, but I've
ruled that out as being the problem). I thought perhaps there was an
issue with how evolution was attaching the file, so I tried outlookE,
Mozilla, and pine, all with the same results.

A hex dump of the temporary file that clamav created shows that there is
a difference between it and the original. In addition the file sizes are
off by one byte, 545 versus the original 544.

Somewhere a trailing nil (or is it NULL?) byte is being appended.

Again, Thank you for taking the time to read this.
