wrong date of emails - how to change?

[Wesley Craig]

INTERNALDATE is stored in the cyrus meta files.  So if you were to  
delete the meta files and reconstruct, INTERNALDATE is set to the  
mtime of the message file.

Your assertion that copy updates INTERNALDATE doesn't sound right to  
me.  What version of cyrus are you talking about?
