Re: what's a good GUI MUA?

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.

You can have (fast) server-side searching with dovecot-solr. (Otherwise it's faster to SSH into the mailserver and use grep -r).
