OK. I think what we're saying is that a format string for creating POP3
UIDLs from IMAP UIDs will solve that particular problem, but it doesn't
solve the general problem of migrating from an arbitary POP3 server to
dovecot. I'm more interested in the latter; if you're an ISP and you buy out
another ISP, you want to migrate their mailboxes transparently but the other
ISP could have been running any POP3 server at all.
