Virtual aliases and "Delivered-To:" header

[Aleš Krajník-2]

Hi guys,

I have a problem setting up my postfix so it records all (virtual) aliases'
expansions into e-mail headers.

I have a postfix 2.6.5, amavis 2.6.3 and (virtual) delivery to dovecot 1.2.6
(on Gentoo which is probably not important).

The thing is that I want e-mail headers to contain all aliases expansions,
for example:
        * i have an alias mysql@... redirected to server@...
        * i have an alias server@... redirected to my personal
e-mail, ales@...
        * i have a virtual mail box, in dovecot, ales@...

These are only examples (of course) and there are more aliases than
mysql@... (otherwise it would not make any sense).

I would like to setup filtering rules in dovecot's sieve so it moves all
e-mails sent to server@... (and all aliases that expand to this one)
to some folder.

I searched through all the Postfix documentation but did not found how to
achieve this. My e-mail headers contain the "Delievered-To:" headers only
for the first and the last e-mail in the aliases' expansion cycle (that is
mysql@... and ales@...).

It seems that some daemon, that does the aliases' expansion (cleanup?), logs
only the first and the last e-mail address in the expansion cycle. So I
tried adding "frozen_delivered_to=no" to main.cf, local daemon in master.cf,
trivial-rewrite daemon in master.cf and some others but the result is always
the same.

So... is there a way how to record all aliases' expansions in the e-mail
headers? Using directly the server@... e-mail address is an option
but not much good for me.

Thanks for your advice!

No. Postfix Delivery agents prepend X-Original-To: for the initial
recipient and they prepend Delivered-To: for the final recipient.

Postfix does not add information to a queue file once it has taken
responsibility for delivery. This absence of queue file updates
minimizes the risk of loss of mail due to queue file corruption.

if your goal is to ease sieve filtering, consider using extensions in
your aliases. for example, redirect mysql@... to
server+mysql@..., ... etc.
