This screams ticketing system or 'in need of better solution.' Take a
quick look at RT (Request Tracker) or some web order system....That said,
yes, mail.app does index IMAP accounts atleast in 10.4 (Mac newb relatively
speaking, I started with 10.4) it does. I don't know how well or if it
indexes bodies and such but the metadata it does. The problem I had with
it was that for me there's just too many old/archived messages (I don't
tend to delete inbox messages...) and it looked like it'd take too long to
index. That said I'm probably going to have to use it anyway since
Cyrusoft (nothing to do with Cyrus nor with this project!) went belly up
(makers of my current client).
Also IMAP has native searching, most of your header fields are pre-indexed,
and you can index the body (in a non-immediate fashion) with squat aka
squatter. This makes IMAP searches fast on any good client. There aren't
many IMAP clients out there though. 'But netscape, thunderbird, outlook,
etc...' NO. Not IMAP clients. POP or NNTP clients taught to parrot IMAP.
They can't do anything until they've downloaded all the headers at the
least, some fetch headers and message structure of every message.
Now in addition tl all of that, I dont' know how Mail.app behaves sharing
folders. We had problems with interoperation on shared folders with as
little as 3-4 people, because one or more of the clients would reset global
flags (deleted and replied are the ones that caused us problems, I'd
imagine they all get tiddled) causing us to lose track of things that had
been replied/etc. Noone used/uses mail.app at the office, it may be fine
(i hope it is) but atleast one of Thunderbird/Moz, Outlook, or Eudora blow
away flags. Not Cyrus' fault at all, it's just doing as told by broken
clients. And we're not even talking race conditions here. Just caching
and enforcing cached state on the remote store as far as I could tell.
