Even if you look for a just _part_ (and not the first part, even) of
the subject?

I use fetchmail to get all my mail, and drop it into dovecot (IMAP).
The only IMAP server I've found that actually stores the _messages_ in
an SQL db is dbmail - it turns out the others I'd heard of are just
using SQL for metadata.

Something like :-)  I meant to add that nothing I know of in KDE makes
that easy, but it can be done. I just tried in Konqueror, and
imap://derek:PASSWORD@localhost/, shows me a directory structured tree
of my mail folders, and I can access the individual mails within.
IMAP has a concept of shared folders that you should be able to use
for password-less access.  Now, I don't know how stable those URLs are
- or if that's in any way controlled by the IMAP spec, because the
message URLs (at least under Dovecot) all contain a numeric prefix
indicating the order they were inserted into the folder.  If copied to
another folder, I'm sure they'd have a different prefix, but I'm not
sure if it would also change if I performed certain operations on the
folder they're in now.
