Kompу меня были проблемы с моим почтовым сервером postfix+dovecot. Каждый раз, когда я пытаюсь отправить письмо на другой сервер (Gmail и т. д.) Я получаю в логе следующие сообщения:
postfix/qmgr[28918]: warning: connect to transport private/smtp: Connection refused
postfix/error[29298]: BB36617ABFB: to=<email@gmail.com>, relay=none, delay=575, delays=575/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)
каким-то образом postfix не может подключиться к postscreen транспорту. Это моя главная задача.cf (с замененными доменами):

мой сервер также работает IPv6, не уверен, что это должно делать хоть чем-нибудь. Если вам нужна дополнительная информация, просто оставьте комментарий 😉
спасибо заранее.
