To add to my question: Is there a imap-command that allows to change the value of internaldate or do I need to implement a series of FETCH,DELETE,APPEND-commands to change the date? So far the APPEND-command is the only way I've found to set the value of INTERNALDATE, but APPEND only is for new messages. I can imagine doing some imapsync and applying the "correct" date. (I can extract a proper date from the mailheaders), but as this is a problem that appears now and then on one of my servers and is asked now and then on the internet, I would like to create a solid solution for this. any help appretiated, thnx peter peter pilsl wrote: > When I copy old emails from one folder to another then the date of this > emails as shown by several clients (OutlookExpress, Thunderbird) is not > the original date but the date when I copied these emails. > > First I thought I can change this date by changing the date of the > actual file that contains a certain email, but this did not work. > > So how can I change the date of a email on a cyrus-imap-server? > > Do I need to delete certain cache-files and reconstruct all mailboxes or > is there a secret (at least to me) command or ...? > > thnx for any advice, > peter > > -- mag. peter pilsl - goldfisch.at IT-Consulting Tel: +43-699-11288470 Tel: +43-1-8900602 Fax: +43-1-8900602-15 skype: peter.pilsl pilsl@xxxxxxxxxxxx www.goldfisch.at ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
