wrong date of emails - how to change?

[peter pilsl]

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
