You should consider getting fd2ftp v0.83beta. 
I has a few fixes for this stuff...
                           
You can get it by FREQ: fd2ftp-a
or ftp://ftp.klock.com/ATKSoft

Let me know if you still have the problem, if you do, I'll
probably need examples of the messages in your NetMail directory.
It's probably breaking on one of the message headers...

Thanx'
