    I mean UIDL string, not formatting string, sorry. But this does not

    IMAP UID is just a number. And it's appearence is fixed. It's not an
UIDL response. Right?

    Just to clarify: there is no importing at all. Dovecot stores UID and
UIDVALIDITY internally and basically it's compatible with uw-imap. But the
UIDL command answers via POP3 is different. So, I need to be able specify
formatting string for the UIDL answer. This does not requires any changes
for old messages and for the new ones. I'm just want sit fixed at %08x%08x
format forever and do not want to switch to %u.%u used by dovecot...
