Good day, Gents.

We are running: dovecot 1.2.17 dovecot-1.2-sieve-0.1.19 dovecot-1.2-managesieve-0.11.13 postfix 2.4.3 on OS X 10.5.8 server. Only about 15 users access the server. No problems.

My question is... what would I have to upgrade, and to what version, in order to take advantage of pigeonhole sieve's duplicate detection (vnd.dovecot.duplicate) functionality?

Thank you very much.

Bruce
