Fixed a vexing bug caused on POST w/ Thunderbird

When Thunderbird sends a short article, it may split the body's final
delimiter "." into a separate transmission of just that with the final
\r\n terminator.  When that occurred, a bug occurred where it was
treated as a new message to Post, which would hang on the connection.
Fixed.
