What mail server should I put on a Linux Web Environment?

Question

linux

Какой почтовый сервер поставить на сервере с Битрикс веб-окружением Linux (1 выделенный сервер, не веб-кластер)?
Необходимо поставить именно свой почтовик, чтобы иметь возможность настройки квот, итд.
Сам склоняюсь к пакету iRedMail (Postfix, Dovecot, SpamAssassin, ClamAV, RoundCube)

Кто тестировал, кто ставил, успешно ли применять такие решения.

Answer 1

Not the best solution to install a mail server on a server with Bitrix.
Mail servers can take tens of gigabytes, taking into account all the logs, and this is for several dozen users for half a year of work. If you have such a task for security purposes (storage and processing of letters on your hardware on your software platform), then it would be preferable to allocate a separate server for this. Having easily hacked the leaky Bitrix, getting access to the server and mail is not so difficult. Naturally, Bitrix can and should be isolated as much as possible, but no one has canceled other holes. Given that Bitrix is ​​still installed out of the box on the old version of CentOS and with the old version of php... This is my IMHO.
And traditionally, there can be various problems with mail, if everything is assembled on opensource products, sometimes you are ready to sort out rather non-trivial tasks and think about why certain guys consider your server to be spam, and how to get out of the black ip\domain list of the largest google mailer or what because of one wrong header, letters on Yandex are not accepted. All this is good and cool, but I insisted on using Exim transport to the SMTP servers of Yandex and other mail providers.
If after all this you can't be stopped:
Not a bad solution, www.zimbra.com - visually looks the best, installed on CentOS
You can try and configure www.iredmail.org, I won't tell you about it.

Answer 2

ты знаешь отойдя от msmtp битрикс вм кастомится, больше кастома тяжелей обновлять.
Так же встанут реальные трудности с DKIM DMARC и так далее, посколкьу если опставить самих демонов можно, и прописать ручками тоже все можно, Но про автоматизацию и обновления можно смело забыть.
В таком вопросе внешний сервис смотрится очень даже достойно ;(.
