amavis

Hello, I installed amavis as per Rainer Link's advice however now after scanning the sendmail takes on the uid of the sender with a configuration file of sendmail.orig.cf whcih brings delivery problems since only root is allowed to write to the mailqueue I have had to make mqueue 777 in order for mail to go. Which is totally undesirable. Someone please help. I tried what it says in BUGS and changed the mlocal lines in both file to add an o and remove the S but things still do not work.
