Question: will this apply to all UIDs or just to those for new mail? I can't tell from the code fragment.
In may particular environment this applied to all messages. Taking inaccount that old messages was served by uw-pop3 they will not refeteched by POP3 clients after the upgrade to dovecot.
I understand your motivation.
There are two requirements:
- major: a UID that any client may have seen _MUST NOT_ change.
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.
No, but the UID must be stored UNLESS the format is perpetual. How do I tell Dovecot which format $ANY_OTHER_SERVER used? What if the server used MD5? Will we see dozens of plugins? Or would not it be more sensible to just give it a list of UIDs?
This could be achieved by a little program that runs once per mailbox after the initial switch. There is no need for this. The only thing is needed - is just an ability to specify the format string in the config file and use this forever. So, for existing dovecot configuration (default) it will be like
pop3uidl = "%u.%u"
while for uw-imap migrated environment it should be changed to
pop3uidl = "%08x%08x"
This won't catch all cases, as above.
