Ok someone on the postfix provided another solution. Here's the

My general rule for working with LMTP is to act as if Postfix was merely
relaying over the network.

relay_domains = example.com
transport_maps = hash:/etc/postfix/transport

[email protected]        lmtp:[192.168.1.1]
[email protected]        lmtp:[192.168.1.2]
....

relay_recipient_maps = hash:/etc/postfix/relay_recipients

[email protected]                OK
[email protected]                OK

Generating relay_recipient_maps and transport_maps from a single storage
table (or directly using them from LDAP via appropriate queries) is left
as an exercise.

I tried this kind of setup, file based, and it all works, I was even  
able to test virtual_alias_map.

So the current sictuation is:
  - Every virtual domain will be relayed trough lmtp to the correct host
  - virtual domains will be defined in relay_domains
  - Address mapping will be done via relay_recipient_maps
  - Aliases will be done via virtual_alias_maps, the file based  
approach I used was mapping [email protected] -> [email protected]

What still needs to be figured out is how exacly does the forwarding  
works because I tried [email protected] -> my_user@my_isp.com in the  
virtual_alias_maps but postfix actually tries to connect to my_isp.com  
instead of mail.my_isp.com, but this is probably me that actually does  
not understand how this works with postfix; Canonical domains also  
needs some looking into it(did I told you that I'm new to  
ISPMan/Postfix/Cyrus? :) )

And what definitly needs some look is how exactly are we gonna define  
the ldap lookups for the transport maps.

Every help on the subject is more than welcome.
