This is by way of a sanity check; I believe something is not possible to
do in Postfix without resorting to external code, but would be very
pleased
if I was proved wrong.
Suppose I have a catchall delivery for a (virtual) domain into a
mailbox:
@domain => A
I also have a couple of other addresses in the same domain delivering to
their own mailboxes:
p...@domain => B
p...@domain => C
So far so good, easy to set up and things work as expected. Now for the
complication. In addition to the fully qualified addresses delivering to
their own mailboxes I require a copy of this mail delivered into the
catchall mailbox:
p...@domain => B, A
p...@domain => C, A
Now, providing I'm prepared to do an address rewrite I can set this up
as
follows:
virtual_alias_maps = hash:virtual_aliases
virtual_mailbox_maps = hash:virtual_mailbox_recipients
virtual_aliases:
p...@domain p...@domain catch...@domain
p...@domain p...@domain catch...@domain
virtual_mailbox_recipients:
@domain A
p...@domain B
p...@domain C
The problem is that I don't want to see that rewrite to
catch...@domain being
done, because of just one more little complication. Instead of
delivering to
mailbox A, I want mail that would arrive there sent on to another MTA,
so my
configuration looks like this:
virtual_alias_maps = hash:virtual_aliases
virtual_mailbox_maps = hash:virtual_mailbox_recipients
transport_maps = hash:transport
virtual_aliases:
p...@domain p...@domain catch...@domain
p...@domain p...@domain catch...@domain
virtual_mailbox_recipients:
@domain OK
p...@domain B
p...@domain C
transport:
domain smtp:[MTA]
p...@domain virtual
p...@domain virtual
If I allow that address rewite then mail for p...@domain or p...@domain
will get
sent on to the MTA with an envelope recipient address of catch...@domain
rather than their original recipient address.
I've tried various work arounds without success. The one that seems most
natural, but which DOES NOT WORK, is the following:
virtual_aliases:
p...@domain @domain p...@domain
p...@domain @domain p...@domain
This results in mail for either address only arriving in their own
mailbox.
Is there another approach to this that I'm missing?
