Postfix configurations: sendmail only

NOTE:

I believe this is both postfix and dovecot...

Locations

/etc/mail/mailer.conf

?

Install

FreeBSD

Install

sudo pkg install postfix
#( when asked to activate postfix in /etc/mail/mailer.conf say YES )

Add user postfix to group mail

pw groupmod mail -m postfix
hostname             # Verify your hostname is an FQDN
sudo newaliases      # (Re) Aliases file (mail aliases)

Enable postfix, Replace sendmail

# /etc/rc.conf

hostname="mercbugs.mfwbugs.com"  # required suffix of domain.com so that it looks like a FDQN (email will be from bugzilla@mfwbugs.com)
postfix_enable="YES"


# FreeBSD includes sendmail, which we will be replacing with postfix.
# You can inform your system which executable to use in rc.conf/periodic.conf
#
# Disable Sendmail (for postfix)
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_enable="NO"
