Postfix mail distribution in multiple domains

lq_win · 11-30-2016, 07:43 PM

Hello,
I am running Postfix for Multiple domains, I put domains in /etc/postfix/domains

mydomain2.com #domain
mydomain3.com #domain

in main.cf
mydestination = mydomain1.com, $myhostname, localhost.$mydomain, localhost, /etc/postfix/domains

alias_maps = hash:/etc/postfix/aliases
alias_database = hash:/etc/postfix/aliases

everything works properly

now I want to create some distribution emails with the same name, for example:

support@mydomain1.com --> john@mydomain1.com, sarah@mydomain1.com
support@mydomain2.com --> merry@mydomain2.com, roben@mydomain2.com
support@mydomain3.com --> tony@mydomain3.com, winan@mydomain3.com

what format should I use in my /etc/postfix/aliases?

please help
thanks

You have:

The simplest method to host an additional domain is to add the domain name to the domains listed in the Postfix mydestination configuration parameter, and to add the user names to the UNIX password file.

This approach makes no distinction between canonical and hosted domains. Each username can receive mail in every domain.

The limitations of this approach are:

A total lack of separation: mail for info@my.host.name is delivered to the same UNIX system account as mail for info@example.com.

Postfix virtual ALIAS example: separate domains, UNIX system accounts

With the approach described in this section, every hosted domain can have its own info etc. email address. However, it still uses UNIX system accounts for local mailbox deliveries.
