Generally you should post your own thread and give us some server information so we know how to tailor our replies. Since you haven't really given us anything to go on I have some general questions:
Do you have php5-imap installed? This php package is required for polling mail.
Have you configured cron or Windows Task Scheduler to run the cron.php?
thank you ntozier for the reply
i will try to answer your questions ,
-yes i do have cron set ( took me through loops though )
-yes i have imap installed
in addition , i am using windows 2008 server for deployment in an in-house environment with a 2007 exchange server
from the wikis , i felt that piping would have been most suitable for me ( i could be wrong) but then i can't identify how to set it up in my kind of environment
