STARTTLS and FreeBSD
I can never find a good set of instructions for enabling STARTTLS in FreeBSD and sendmail. The one I keep coming back to is this STARTTLS section in this OpenBSD set, as the pathnames all match: http://www.dsrw.org/~dlg/sysadmin/sendmail/
It’s really quite easy, and there’s no excuse for any one, and certainly no excuse for any service, to not turn STARTTLS for SMTP on.
