Hi,
I am using Dovecot LDA as LMTP renders envelope extension unusable.
The problem I have noticed is that when user has multiple aliases sieve
responds to all of them, not only to :addresses specified.
>From testing it seems that :addresses only adds addresses to the list of
"known" emails to check against. It is not limiting it.
As I understand, sieve should check if To: header is consistent with
addresses known to be users. But how Dovecot knows about aliases
assigned to the user?
>From my testing if header To: address is consistent with envelope To:
address the reply is fired. I have sieve_vacation_use_original_recipient
left at it's default value (no), so that shouldn't be the case. Now if
user addr...@example.com has alias al...@example.com specified, the
vacation reply will be sent to email addressed to al...@example.com,
which is weird, because this behavior should be enabled by switching
sieve_vacation_use_original_recipient to yes.
When user receives an email that was originally sent to his gmail
account (forwarded) there is no reply. If I add gmail address to
:addresses reply is generated as expected.
So my main question is if this is expected? I would like to enable only
delivery to primary address and to + extensions to that address by
default.
I think that it might be that Postfix is expanding aliases and passing
the final recipient (as to=<XXX>) to dovecot. Then dovecot is using that
address to check for explicit delivery, but something fails, as this
address is obviously not in To: header. So it looks like orig_to has to
be used as well which should be disabled by
sieve_vacation_use_original_recipient?
My address is: ka...@augustin.pl, alias is: ca...@augustin.pl
