Notice the *very* small difference in the format between UW's ipop3d and the ones mentioned a little bit below?
IIRC, the difference is intentional -- I believe the stated reason was that the mail UID (%u) is more unique than UIDVALIDITY (%v), so the default format has the UID at the beginning just in case the client truncates the UIDL.
