CORRECTION: It is happening to just plain text messages as well.   What 
should I be looking for to determine why Mailscanner is thinking 
messages have 0 byte attachments when I can't find anything in the qf or 
df files in the quarantine that look like any sort of attachment is 
included with the email?

Does the fact that the error message states that the attachment is too 
large in one spot and too small in another indicate anything special 
that might point me in the right direction to troubleshoot?    I've been 
using MailScanner for years and have never had a problem upgrading 
countless times before, but this is occuring on more then one server 
since I upgraded yesterday.
