Pop3 email download problem

[Jack <ostroffjh sbcglobal net>]

Hello all,

I've been running 2.5.1 for a while now with no problems.  However, I  
now have a message which will not download.  Actually, balsa does seem  
to download the message, but doesn't seem to recognize it has finished,  
and times out.  This is from AT&T/Yahoo.  Below is the POP3 debug  
output.

After the line with the single '.' balsa just sits there for about a  
minute, and then issues the rest of the debug messages, and pops up an  
error "POP3 Error: POP3 connection severed."  The POP messages after  
the "." are the same, even if there are other messages waiting to  
download.

Thanks for any thoughts or ideas on how to fix or how to debug further.
