Eric, like I already told you (October 7, 2008) this is NOT the right
way to do this and leaves your code vulnerable to many, well known,
attacks. *You* might want to continue using this (I can't force you to
do it correctly) but please don't publicize this as a workaround. Keep
in mind that what _may_ work for a quick-hack can be potentially
disastrous for others.


Toutu, have a look at http://go-mono.com/forums/#nabble-td19851624
thread. In particular the parts about using SMTP port 587 for
submission. If that does not work please open a bug report and include
(part of) the code you're using.
