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.
IMHO that's a good thing. I know some people in this list think they want deduplication, but sometimes when I'm later replying to a message (I've messages over a month old I know need replying) they really would prefer for it to be shown in they inbox when I finally reply to them rather than dovecot list mailbox (which they never end up reading then).
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?
I'm not planning on implementing anything like that.
