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

Hello everyone,

I've just started using 1.0-beta3 on Ubuntu Dapper, having migrated
from an mbox / UW-IMAP combination to a Maildir / Dovecot one.  For
some reason the mb2md tool failed to recognise some of my mbox files as
valid ones, so I migrated my email by running UW-IMAP, copying my
folders to local storage in Evolution, then running Dovecot instead and
copying the folders back.

All seems OK, except that in Outlook 98 all the emails now have the
date/time of their migration, not when they were received.  This isn't
a problem in Thunderbird or Evolution - but my wife uses Outlook and
doesn't wish to switch.

I've tried using touch to change the timestamps of the mails in my
inbox (in ~/Maildir/cur) but this hasn't had any effect.  I've also
tried deleting ~/Maildir/dovecot.index and
~/Maildir/dovecot.index.cache but this hasn't made any difference
either.

Something else in dovecot must be being sent to Outlook as the date /
time on these emails.  Can anyone suggest what it would be and how I
might go about changing it (to, for example, the Received: date on the
email header?).

Thanks in advance,
James.

I've had the same problem when migrating one dovecot system to another
using "scp -r" to copy the maildirs.  "scp -r -p" fixed the
problem.

Updating the files' mtime timestamps and removing dovecot.index.cache
does update them from Dovecot's point of view. I guess your problem is
that Outlook already cached the mails locally with wrong timestamps, in
which case the easiest fix would be to change uidvalidity field in
dovecot-uidlist (second field in first line) file to force a resync.

tried this without any luck (& it made Outlook crash the first time it ran
after the change).  However, deleting the 192.168.xx.xxxxxx.pst file in
c:\windows\application manager\microsoft\outlook did work, so my problem is now
resolved.

Thanks,
James.
