Hi,
Up until now I've been using Postfix for one domain, evidently with
just one configuration, using the virtual domains approach. Now I'm
in a situation where I need to handle another completely different
domain, with a different behavior and a different Postfix
configuration, on the same server. My question is: Should I use the
Multi Instance approach
(http://www.postfix.org/MULTI_INSTANCE_README.html) in this case?
I'm asking because I'd need to use the same server public IP for
both instances, and I don't know whether Postfix would create two
different processes (one per each instance), which would mean I need
at least a different port (and I even found several examples where
each configuration has its own IP address), or if both
configurations are handled by the same process.
If the Multi Instance approach is not suitable for this scenario,
would someone recommend another way to face it?
Thanks,
Nicolás
If you only have one public IP, you are limited to one postfix instance.
Postfix can natively handle multiple virtual domains, each with its
own recipient list.
The details of "different behavior" determine if this is even
doable. Some postfix settings are configurable per recipient
domain, others are not.
Actually, on second though, the "different" part just implies that one
of the domains should run a check_policy_service in its
smtpd_(sender|recipient)_restrictions, and the other one would not. I
don't believe this is configurable per domain, but I can make the
service return 'DUNNO' if the evaluation corresponds to the domain that
doesn't need to, as a workaround.
Hosting another domain may be as easy as adding another domain to
virtual_mailbox_domains and adding the recipients to
virtual_mailbox_maps.
Yes, that's exactly how it's configured now, so I guess I'll follow the
same schema as I'm limited with one public IP address.
Thank you!
Regards,
Nicolás
