Postfix and multidomain

Question

I'm trying to setup postfix to use multi-domains mail.

Right now, I can send mails to user@ns3289160.ip-5-135-180.eu, but sending mails to user@domain2.com isn't working: I receive the following email while trying to send emails to this address

Delivery to the following recipient failed permanently:

     user@domain2.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain domain2.com by redirect.ovh.net. [213.186.33.5].

The error that the other server returned was:
550 sorry, no mailbox here by that name (#5.1.1)

main.cf

myhostname = domain1.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = ns3289160.ip-5-135-180.eu, localhost.ip-5-135-180.eu, localhost
virtual_alias_domains = domain2.com
virtual_alias_maps = hash:/etc/postfix/virtual/addresses

/etc/postfix/virtual/addresses

domain2.com         DOMAIN
user@domain2.com    user

I genuinely have no clue about what's going on, knowing that I never switch my MX entries on my domain name (it still points to redirect.ovh.net, that stands for, according to their documentation, the mx for personnal mailboxes).

How can I properly set everything up so that I can be able to use postfix with a personalized mail address ? (such as domain1.com instead of ns**.eu)

The names domain2.com, user have been changed...

well, that's the problem. Please setup mx record of `domain2.com` to your server. — masegaloeh, Apr 02 '15 at 22:33

If you would like to receive mail with your VPS, you need to point the MX to your server. Now it's pointing to redirect.ovh.net so the virtual aliases has to be configured there as redirects, not destinations. You could have for example:

mail.example.com.   IN   A     5.135.180.55
example.com.        IN   MX 1  mail.example.com.

This is not a Postfix issue and your Postfix is probably configured correctly. Just remember to postmap the virtual alias table if it isn't.
