Поставить почтовую систему Postfix (smtp), Dovecot (Imap, pop3), должно работать исключительно на host.local. Должно быть 3 ящика между которыми ходят письма.
Поставить Thunderbird(должен подключаться к почтовику по POP3 и Imap) и к нему подключить 3 ящика.

#создаем группу и юзера vmail и загоняем пофтфикс и довкот эту группу, чтобы они могли смотреть файлы друг друга, остальное говно будем запускать от юзера vmail 

groupadd -g 4048 vmail
useradd -s /usr/sbin/nologin -u 4048 -g 4048 vmail
usermod -aG vmail postfix
usermod -aG vmail dovecot

#тупой довкот не умеет по умолчанию в свой лог
touch /var/log/dovecot.log
chown vmail:vmail /var/log/dovecot.log

сдлаем файлики для юзеров и доменов

#фигачим сертификаты

запихиваем конфиги, которые я тебе дал
/etc/postfix/main.cf
/etc/postfix/dovecot.conf
и важно, чтобы в /etc/postfix/master.cf внизу было:


dovecot unix    -       n       n       -       -      pipe
    flags=DRh user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain} -m ${extension}


перезапускам сервисы
service postfix restart
service dovecot restart

отключаем selinux на всякий


создаем скриптик для новых юзеров, я тебе его дал
делаем юзера и вперед
