Ok, I will be send you patches created with "diff -u" in the future.

Sorry, I work mainly under win32 and API under win32 differ from API 
under linux. I hope now I have correctly improved API.

I'll send you this trace later.

I know that comcast.net SMTP server is not conformant to RFC 2821. But 
comcast.net is real SMTP server and without this functionality we don't 
be able correctly work with it. In addition this functionality not affect
working with correct SMTP response.

Also, I have found another problem related to sockets. When I debug
my program under Linux, signal SIGPAPE often appear. I tried to solve
this problem. I have added possibility to set flag in mailstream_low.
If this flag is set, command "send" call with MSG_NOSIGNAL flag in
arguments (look at the patch).
What do you think about it?
