I'm not clear on why sendmail is a required MTA, and wonder why you are not implementing an alternative.
Any functional alternative. Based on your comments in this thread and the feedback you received in your
other thread on the same subject...
- You cannot obtain sufficient guidance or documentation for provisioning sendmail for your requirements.
- What little guidance that was provided in your other thread came from me, but was apparently insufficient.
- All OSes that have (or used to have) sendmail as their default MTA have provisioning widgets to deploy alternatives. FreeBSD included.
As an example, here's an OpenSMTPd configuration file for a smart host that uses TLS to encrypt traffic, extracted from the first example in the smtpd.conf(5) man page:
Code:
listen on lo0
table aliases file:/etc/mail/aliases
table secrets file:/etc/mail/secrets
accept for local alias <aliases> deliver to mbox
accept for any relay via tls+auth://label@smtp.example.com \
auth <secrets>
