Install postfix and cyrus-sasl2 from ports.

in /etc/rc.conf:

sendmail_enable="NONE"

in /etc/periodic.conf:

daily_clean_hoststat_enable = "NO"
daily_status_mail_rejects_enable = "NO"
daily_status_include_submnit_mailq = "NO"
daily_submit_queryrun = "NO"

drop in a default aliases file:

cp /usr/local/etc/postfix/aliases /etc/aliases

Create a copy of sample-main.cf and customize. Important bits are:

# sasl config
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
broken_sasl_auth_clients = yes

smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

# tls config
smtpd_use_tls = yes
smtpd_enforce_tls = no
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /usr/local/etc/apache/CA/server_key.pem
smtpd_tls_cert_file = /usr/local/etc/apache/CA/server_cert.pem
smtpd_tls_CAfile = /usr/local/etc/apache/CA/cacert.pem
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
smtpd_tls_loglevel = 1

For cyrus Change the cyrus lines in master.cf to:

cyrus     unix  -       n       n       -       -       pipe
 user=cyrus argv=/usr/local/cyrus/bin/deliver -r ${sender} -m ${extension} ${user}

Enable cyrus as the mailbox transport in main.cf:

mailbox_transport = cyrus

For courier

home_mailbox = Maildir/
