I've had a number of Dovecot installs happily running for quite a few years now, but I've just stumbled over a new issue. I am trying to get some iPhones to do server-side email searches through ActiveSync/Exchange protocol -> Horde -> Dovecot.
The bit I can't figure out is if I need to enable and configure FTS in Dovecot for that to work? I've tested server-side email searches against the same Dovecot server on Thunderbird - through IMAP (there is an option to force the search on the server in Thunderbird) - and it is working really well and fast. I am only really interested in Sender/Recipient/Subject searches.
Server-side searching is not working at the moment on the iPhones side - although I can see the ActiveSync commands being sent to Horde. Anyway, to begin with, does anybody know if server-side IMAP searches need FTS in Dovecot (Horde is talking to Dovecot through IMAP).
The fact that they work fine in Thunderbird would suggest the answer is 'no' - but could someone confirm that is correct please?
Anticipated thanks for any hints. I am on Dovecot 2.2.33 if in case it matters.
