Answer 1

PDD from Yandex

Answer 2

On ubuntu - https://workaround.org/ispmail/jessie
It's true for debian jessie, but it shouldn't make much of a difference.

Answer 3

Under ubuntu:
A lot of memory and you need a beautiful web muzzle: Zimbra
I want to save resources, - bare postfix
Under Windows:
For example hMailServer
I don’t want to bother at home - traffic rules from Yandex with Yandex web muzzle.

Answer 4

Of course on bubuntu. SMTP server for receiving from the world and sending mail to the world + IMAP server for local delivery (+ webmord but this is optional). I deliberately do not name the programs, because there is a choice. Small, but there is - for example, for me it is sendmail + dovecot (+ webmorda on horde). It would be better to take care of the PTR record right away - there are incredulous servers that have an automatic name, which will give the provider consider suspicious.
