Re: [Dovecot] A message, when moved by multiple clients with same account and same filters, can be duplicated by filters on destination imap folder.

The fact is that this was perfectly working with wu-imap (without any duplication/triplication of emails).

That's because UW-IMAP (with mbox) allows only a single IMAP
connection to access the mailbox at the same time (new connection
kicking out the old one). There never were multiple clients connected
to it at the same time.

I don't really have any good solutions for this, except how about
trying to get rid of client-side filters and use Sieve instead?
