> Virtual alias maps apply to all domains.
Uhm... ok,.. but for what is virtual_alias_domains then good for?
See: http://www.postfix.org/ADDRESS_CLASS_README.html
I've had read this before,.. but still did not understand the need for
virtual_alias_domains.
Now I think I might:
- virtual aliasing always takes place, as you said before
- the envelope recipient address might be rewritten to any address
- if the resulting address has a domain part which is already a local,
relay or virtual mailbox domain it should be accepted
- but if not, and the mail goes to some remote domain, the mail would
be rejected (unless the MTA is an open relay)
=> Therefore one has to "whitelist" the virtual alias domain...
Does this make sense?
I found some other things in the documentation where you could perhaps
have a short look at:
I'll let someone else double check these.
Thanks!
Best wishes,
Chris.
