Dovecot performs indexing of all the maildir folders that it accesses, which should help performance on the IMAP server side. You then need a MUA that doesn't download all of the messages whenever you access a folder. If memory serves, Thunderbird does this in order to support better text searching, but obviously this has performance consequences.
I want the client to download all the mail so I can use my laptop with poor or no Internet access. So while Dovecot indexing is a good thing, it's not going to be a big deal for me.
Just be aware that there is an incompability / bug in some versions of Thunderbird and the Dovecot IMAP implementation, where it will download *all* the mail and not just recent unread ones every time a sync takes place between the imap server and your client, if you set it to keep a local copy of all your mails. So if you have regular syncs (like every 15 mins) you can end up downloading several GB of email data daily, as what happened to me a while ago. Upgrading Thunderbird fixed it. But it is apparently a specific Dovecot-thunderbird version issue only. So if you do go that way, just check thats not happening. D.

Evolution last I used it was not particularly reliable, and had a reputation of being unreliable and poorly supported. It has been a while since I used it, so I can't remember the details with the problems I encountered. Although I do seem to vaguely remember sometimes your configuration can get "corrupted" and require purging in order to restart evolution.
One problem with Evolution is that it had it's own database of mail. I'd rather have the local mail store be in Maildir format so I can be confident of my ability to rescue mail without much effort if things go wrong.
Using Maildir storage plus indexes is good, so something like Dovecot's indexes for local store of the offline IMAP would be good.

If indexed mail is your preference, have a look at:
This works best on a local Maildir however. In fact a local Maildir might be the only thing it supports (I can't remember right now), which may mean it is insufficient for Russell's requirements.
Proper indexing is a good thing. One thing that really annoys me about Kmail is that it indexes fields like the sender for a quick search but then doesn't use those indexes for a full search. For example I have a folder containing 15,000 mailing list messges of which about 100 are from Brian May. I type "Brian May" into the main search field and get an instant list of the 100 messages, I do a search for "Brian May" as sender and a random technical term and my hard drive grinds for minutes when it really should just be searching those 100 messages for a match on the technical term.
