Please stop replying to me personally. See
http://www.eyrie.org/~eagle/faqs/questions.html

To "do something about it" you modify the openssl source code so that it
sends the correct SMTP sequence (EHLO, wait for reply, STARTTLS).

If it "works" on your gentoo-linux box, pointing to the same smtp server,
then I can only guess that your gentoo-linux box is running a different or
patched version of openssl. You can run the session from there and use
tcpdump to show what is different in the message exchange. If it's a
different version of openssl then try installing the version of openssl
which is in the ports collection.

If you reply to me again personally, your message will go straight in the
trash.

Regards,

Brian.
