make install

ee /usr/local/etc/postfix/main.cf

# -------------------- main.cf -----------------------------------------
queue_directory = /var/spool/postfix
command_directory = /usr/local/sbin
daemon_directory = /usr/local/libexec/postfix
mail_owner = postfix
unknown_local_recipient_reject_code = 550

debug_peer_level = 2

debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
xxgdb $daemon_directory/$process_name $process_id & sleep 5

sendmail_path = /usr/local/sbin/sendmail
mailq_path = /usr/local/bin/mailq
setgid_group = maildrop
html_directory = no
manpage_directory = /usr/local/man
sample_directory = /usr/local/etc/postfix
readme_directory = no

mydomain = example.com
myhostname = mail.$mydomain
myorigin = $myhostname
mydestination = $myhostname, localhost,$mydomain

mynetworks = 192.168.10.0/24, 127.0.0.0/24
mynetworks_style = subnet
# --------- end of file main.cf --------------------

Добавьте в файл /etc/rc.conf
postfix_enable="YES"

Если вы имеете несколько доменов, то необходимо изменить параметр:
mydestination = $mydomain, $myhostname, $transport_maps, localhost

postmap /etc/aliases

/usr/local/etc/rc.d/postfix start

Проверьте /var/log/maillog на отсутствие ошибок.

2. УСТАНОВКА DOVECOT

cd /usr/ports/mail/dovecot
make install

Отредактируйте /etc/rc.conf

dovecot_enable="YES"

ee /usr/local/etc/dovecot.conf

# ----------------- /usr/local/etc/dovecot.conf ---------------------
protocols = imap pop3
disable_plaintext_auth = no

user = root
}
dict {

}

plugin {
}
# ----------------- end /usr/local/etc/dovecot.conf ----------------

Проверьте файл /var/log/messages and /var/log/maillog на отсутствие ошибок.
