[Dovecot] changing INTERNALDATE or similar

[Karl Rudnick]

I have a question which others must have encountered. I switched from
uw-imap to dovecot-imap a few months ago and moved my fairly large mail
archive (~15 yrs) by simply mounting both accounts in a mail app and
simply copying my folders over. This worked well, and all my mail is in
order when I view it in evolution or thunderbird on any number of
machines. However, since our company uses MS Exchange Server, when I add
my dovecot imap account to outlook, everything is great except the
received dates - it looks like the date I made the transition, but in
all instances it's not simply the time stamp in the Maildir folder. I
googled around on this and have gathered that this date is coming
somewhere from within the dovecot index file. Is there a utility for
scanning that so I can ascertain where the date shown in Outlook is
coming from? Is there also a utility which would just reset the
INTERNALDATE (or whatever it is that Outlook is keying on) to the date
in the message on the "Date: ..." line?

This issue is not life threatening as I don't use Outlook much, but when
I do, it is confusing to not have the "Received" column be meaningful,
especially for sorting.

Thanks for any help - Karl
