echo 'postfix_enable="YES"' >> /etc/rc.conf
echo 'dovecot_enable="YES"' >> /etc/rc.conf

service postfix start

FreeBSD: postfix, dovecot

# POSTFIX SMTP SERVER

/etc/rc.conf
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

killall sendmail

cd /usr/ports/mail/postfix && make all install clean
[x] BDB         Berkeley DB support     
[x] TLS         Secure network connection support via TLS  

Would you like to activate Postfix in /usr/local/etc/mail/mailer.conf [n]? yes

/etc/rc.conf
postfix_enable="YES"
dovecot_enable="YES"

cd /usr/local/etc/postfix
cp main.cf main.cf.ORIG
cp master.cf master.cf.ORIG

pw groupadd vpostfix && pw useradd vpostfix -g vpostfix -s /usr/sbin/nologin -c "Virtual Postfix user" -d /var/empty
grep vpostfix /etc/passwd
# vpostfix:*:1002:1002:Virtual Postfix user:/var/empty:/usr/sbin/nologin

main.cf:
myhostname = test.local
mydomain = test.local
myorigin = $mydomain
inet_interfaces = all
home_mailbox = Maildir/

# myhostname = test.local - FQDN name of server

# Далее добавьте в конец файла

# Virtual domain config
virtual_mailbox_domains = /usr/local/etc/postfix/virtual_domains
virtual_mailbox_base = /var/mail/vhosts
virtual_mailbox_maps = hash:/usr/local/etc/postfix/vmailbox
# Make sure you replace these UID:GID numbers
virtual_minimum_uid = 1002
virtual_uid_maps = static:1002
virtual_gid_maps = static:1002
virtual_alias_maps = hash:/usr/local/etc/postfix/virtual

cd /usr/local/etc/postfix/ && touch virtual_domains
virtual_domains:

# Создайте почтовый каталог, каталоги для виртуальных доменов
mkdir /var/mail/vhosts
chgrp -R vpostfix /var/mail
cd /var/mail/vhosts
mkdir virtual-test
cd ..
chown -R vpostfix:vpostfix vhosts

Postfix создаст каталог "Maildir" автоматически и назначит разрешения
Это произойдет, как только электронная почта придет в место назначения

touch /usr/local/etc/postfix/vmailbox
# добавьте всех пользователей, которые получат электронные письма
# пользователи виртуальные, добавлять в систему их нет нужды
user1@virtual-test1.local       virtual-test1.local/user1/
user2@virtual-test1.local       virtual-test1.local/user2/
@virtual-test1.local            virtual-test1.local/catch-all/
user3@virtual-test2.local       virtual-test2.local/user3/

touch /usr/local/etc/postfix/virtual
cd /etc
