We still need an explanation for sendmail! I found nothing better than
http://www.sendmail.org/~ca/email/auth.html which doesn't look very
/usr/friendly to me ;-)
The default sendmail in FreeBSD is not compiled with SASL and does not
do ASMTP. I suppose one must install the sendmail-sasl port for this.
I'm doing that next, but can't test very much with it, due to my setup.
