[Dovecot] duplicates with multiple To/CC and sieve redirect copy
as at 3a.pl
Wed Feb 22 00:46:48 EET 2012
In one installation we are using sieve "redirect :copy" to create copy
of the incoming email (local boss gets copy of its employees mails).
There is a problem when the incoming email has multiple To/CC entries
with local users. Multiple copy/redirects are created (one for each
employee) and there are multiple copies in "boss" account.
Each of this emails has the same Message-ID.
Is there a way to detect those duplicates and discard them when saving
copies into boss account?
There was a discussion on the list a while ago (Feb 10/11, 2011)
mentioning this problem, but with no clear solution.
We are using Dovecot 2.0.15. Mail is delivered via LMTP (MDA/postfix is
on separate machine then MAA/dovecot).
