One Postfix and multiple domains, how to do it without Mysql?

Question

Mail server

The task such - how to force to work Postfix with several domains? And not to use Mysql for this - this is some kind of nonsense - I'm not Mail.ru, to get users into the database .... I only need to put a few users on 1 domain, only outgoing mail.
How many manuals I have not met, everyone copy-pastes from each other and everything is offered through the database, but what can you do without it?

Answer 1

Postfix
Dovecot
Correct query in Google.

Answer 2

The answer to your main question is contained in VIRTUAL_README .

everything is offered through the database, and what can you do without it

Absolutely without a DB in any way. Should Postfix get user addresses and passwords from somewhere? But what kind of database it will be - SQL, LDAP or simple files - is another question.
PS It's not clear from your question at what stage of the Postfix configuration you are having problems adding domains. If the question were more specific, then perhaps the answer to it would not be so general.

Answer 3

I did not understand an ear - do you need to receive mail on several domains?
