IMAP Mail Filtering / Moving ??

[jerryyang_la1]

System running : Windows 2003 Server - ActivePerl, PHP, ASP, Mercury32

Are there any scripts (PHP, PERL) that can be used to move IMAP mail
from one folder (inbox) to another folder (junk, spam, kept) ??

Ideally looking at subject or headers ??

My aim would be to call this from Mercury32 and have the script move
the mail to the correct folder in a users mail box..

Thanks
