I doubt dyndns is a reliable way for getting mail server domain name.
Think twice here.

Not with the kernel itself (note: _linux_ kernel), but there is
something special in core/sendmail port: it lacks sasl&ssl support to
get (encrypted) SMTP AUTH. See [1] for that.

Basically you have to add a few lines to site.config.m4 and modify
Pkgfile (+ # Depends on: cyrus-sasl). See attached diff for details.
After installation you should modify /etc/mail/sendmail.mc to listen
for remote requests and such. All that is described at sendmail site.
