No-one had been testing 1.0-tests with Evolution? It was pretty much completely broken with messages having attachments.

• test58's output stream code change were entirely wrong and caused bad breakages with mbox.
• Named pipes are now treated as write-only mboxes (blocks if no-one is reading, perhaps it should timeout in a few seconds?)
• FETCH BODY[n.xxx] replies were all wrong
• LDAP authentication was crashing
• pop3_uidl_format=%f from Andrey

test60 will probably have keyword support. Its index file code is already working, with ability to set over 500k different keywords per mailbox (because message record size is limited to 65535 bytes - should be enough for everyone :). Code is still missing to notify other session about keyword changes, and storing the keywords into mbox/maildir.

For mbox I can use X-Keywords header. There should probably be some configurable limit to how many keywords to set per mailbox.. Dovecot shouldn't mind if the X-Keywords header is huge, but other programs might.

For maildir then.. I think I'll just implement it backwards compatible with 0.99.x, ie. store in maildir filename with a-z letters. That would make max. 26 keywords per mailbox. Except maybe I shouldn't limit it to that. The rest could be stored only in indexes. That however would make it necessary to keep indexes backwards compatible forever so data is not lost.
