Right.This means that a formatting string MUST ONLY have an impact on newly arriving mail. No, there is no need to store the exact formatting string with each message.
He did not say that the formatting string is stored with each message; but there is a requirement that the *UID string* is stored with each message. I mean UIDL string, not formatting string, sorry. But this does not matter.
i.e. changing the format string does not change the UIDs of existing messages; or put another way, the format string is only applied the first time that a new message is seen. IMAP UID is just a number. And it's appearence is fixed. It's not an UIDL response. Right?
Given that, you could apply *any* UID to messages when you import them, and the format string will only affect subsequently-delivered messages. 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...
