[Dovecot] On-delivery deduplication?

Hi,

A feature of Cyrus-IMAPd I really missed after migrated to Dovecot is
their optional "duplicate suppression", which eliminates duplicate
message at deliver time, if their envelope sender, recipient and
message-id matches.  For example, if one subscribes to a mailing list,
and someone hit "Reply All" to reply to him, there will be two different
SMTP deliveries, one from the replier's server and one from the mailing
list.

Is it possible to do the same on latest Dovecot?  (Looking at the
documentation it seems not?)  Or is there some better ways to implement
the same functionality?

Thanks in advance!

Cheers,
