Interesting - I wonder how the kmail guys do it - it seems to work pretty 
well, with only the rarest of false deletions - I had a mailbox with 16k 
messages (deliberately created to test it) which was a double-import of 
another mailbox - I *knew* there would be exactly 8192 duplicates, and kmail 
shot through the file in less than 30 seconds.

If you want to be quick, you can just delete all but one copy of
anything with the same Message-id: header.

If you want to be more thorough, you could additionally generate sha-1
or md5 hashes of all messages as they come in, perhaps inserting them
into a heap.

That's the exact idea I had, except I was thinking of bash and

Yeah, that's good too.

BTW, deduping the addressbook would be nice as well.  A lot of my
addressbook entries have the same e-mail addresses twice - probably as a
result of a failed experiment in which I tried to migrate from jpilot to
evolution for syncing with my palm.
