dovecot - Oct 2006 - Fwd: Received dates problem in Outlook after migration

Having looked at this again, I think I have a hypothesis:

1.  Outlook is ignoring the date/timestamps on the files in my Maildirs
2.  The file names of my transferred files follow a similar pattern
(they start with near-identical numbers)
3.   Dovecot's file naming scheme for mails must relate somehow to the
date that they were created / transferred / received
4.   If I can therefore **rename** the files correctly to reflect their
sending date then I can fix my problem

Does this make sense?  Can anyone point me in the direction of a spec
that says how Dovecot names its files? 

Thanks,
James.

Outlook should use IMAP's INTERNALDATE, which are taken from maildir
files' mtime timestamps. If these timestamps are correct but they're not
showing correctly in Outlook, I'd guess Outlook is caching them
internally. One way to fix this would be to change UIDVALIDITY to force
a coplete resync. You can do this by modifying the second number in
dovecot-uidlist file.

Filenames don't really matter.

Yea. The first number is the UNIX timestamp, but this is done only to
make maildir filenames unique.

Doesn't change anything.
