dovecot - Jul 2013 - Have an issue with catch-all - Dovecot-lda andPostfix

Hi,

I run dovecot version 2.1.7 and postfix 2.9.6.
I'm using dovecot-lda as local delivery.
I use virtual users and need to use catch-all for some of my domains.

My problem when using catch-all is that I got a separate email for each
recipient.
As an example: If I send mail to: test1 at test.org, test2, test3 at test.org,
test4 at test.org and have a catch-all which will send this mail to test at
test.org.
In this example I get 4 mails in my test at test.org inbox and in TO: field in
the header I have all this four recipients:
TO: test1 at test.org, test2, test3 at test.org, test4 at test.org.

In my dovecot log:
2013-07-10 13:49:25 lda(test at test.org): Debug: Destination address: test at
test.org (source: user at hostname)
2013-07-10 13:49:25 lda(test at test.org: Info:
msgid=<20130710114924.DBA3F9FA8D at mail2.test.org>: saved mail to INBOX
2013-07-10 13:49:25 lda(test at test.org): Info:
msgid=<20130710114924.DBA3F9FA8D at mail2.test.org>: saved mail to INBOX
2013-07-10 13:49:25 lda(test at test.org): Info:
msgid=<20130710114924.DBA3F9FA8D at mail2.test.org>: saved mail to INBOX
2013-07-10 13:49:25 lda(test at test.org): Info:
msgid=<20130710114924.DBA3F9FA8D at mail2.test.org>: saved mail to INBOX


My question is if it's possible to receive just one mail instead of four?

If I send the mail via Spamassassin I'll just receive one mail to test at
test.org with TO: test1 at test.org, test2, test3 at test.org, test4 at test.org
in the header.

Thanks in advance
Br
Joakim

perhaps, with some filter or supress doubles etc

you should solve your problem in not using catch alls in the first
line

Where do you use "catch-all" in Postfix or Dovecot?

If you must use Dovecot's "catch-all", Postfix is calling the
Dovecot LDA
for times, so you end up with four copies.

You could try to change to Dovecot LMTP, maybe it is detecting the 
duplication.

Can you activate catch-all in Postfix, then Postfix is to detect the 
duplicate recipients.

How do you send a mail via Spamassassin?
You know that the "to" header is used in only very rare cases for mail
routing, in other words: "to" has nothing to do with mail routing.
