Can this new mail be named identically, i.e.

Hmm you mean no ? Can a new message filen the same name as an old
message ?
Right. I meant file maildir filenames are always globally unique when
they're created.
dovecot-uidlist is recreated lazily. So it may list files that have already been deleted. So when Dovecot notices that there exists a new file that's already listed in dovecot-uidlist but that has been
expunged from Dovecot's index files, it'll figure out the message is
unexpunged and to avoid breaking IMAP clients it'll log a warning and give a new UID to the file.You mean when a client deletes a message, it is first deleted from
index, and then deleted from dovecot-uidlist only if it reappears ? So dovecot- uidlist would grow infinitely ?
In v1.1 dovecot-uidlist gets recreated (causing deleted records to be
dropped) when more than 25% of it contains deleted records.
Or maybe it is cleaned when UIDs have to be rearranged ?
This should never need to happen in normal operation.
