Just dovecot-uidlist.

I don't get that : do indexes store UIDVALIDITY ? nextUID isn't enough to
guaranty mailbox instance uniqueness, right ?

And, same as in my previous answer : why would they get new UIDs ? As they will
be "sorted" (maybe because of INTERNAL DATE) in the same order ? When I erase dovecot-uidlist manually, it gets
recreated with the same UIDs (but I didn't delete indexes though)...

Same as above : I cannot get them to change in a test situation where I delete
dovecot-uidlist, send a new mail and check mail again.

Thanks
