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.

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.
