Subject: Re: Redirection using a 1:1 & domain wildcard alias
Date: Mon, 5 Oct 2020 20:38:00 +0000
Thanks Jaroslaw,
Is any of this documented anywhere? I’ve read virtual(5),
virtual(8), cleanup(8), etc. ad nowhere in the observed behavior
documented.
There’s discussion as to order to table searching and address
matching but nothing that I’ve seen discusses what happens when
there is both a user account and an alias configured nor when a user
account and a domain wildcard alias are configured concurrently.
If this is all “just understood to be true”, then fine…but if
so, would be far better to document this stuff…
On the flip side, if I’ve simply missed it, fair enough…just would
like to know where…

Because that's exactly what aliases are meant for - to deliver mail
to the
alias target *instead* of the original address.
If you want the mail to be delivered *both* to alias target and to
the
original address, you must alias the original address to a *list* of
both
these addresses (I don't know if it works for virtual_alias_maps, it
certainly works for aliases defined in /etc/aliases)
* When a domain wildcard alias & a user are configured, why are
emails sent to the user only delivered to the user and no copy to
the alias target?
Because domain wildcard alias applies *by definition* for any address
in
the domain that *does not have* it's own alias defined. Once an
address has
it's own alias defined, wildcard alias is ignored.
