Agreed.  I've used Balsa for years with no problems in that regard.  
mail-file-so on the other hand probably has the --crlf option's default 
the wrong way round, making this a trap for the unwary.  I wasn't clear 
if the problematic message was via balsa or mail-file-so.

Agreed again unfortunately. I can't think of a way to construct things 
otherwise to work round this one.  Tracing a session with the server 
using Wireshark might shed more light than strace, just now I'm out of 
suggestions.
