[MM3-users] Permission Denied "/opt/mailman/mm/var/archives/..."

I am writing my own archive reader script in PHP which parses the "maildir" content produced by the "prototype" archiver.

When I try to access the contents from "opt/mailman/mm/var/archives/prototype/LISTNAME/new" folder I get a permission denied error.

*** I'm using the "file_get_contents" PHP command to access the file. ***
