This limit is intentional. If you allow DOMAIN_ADMINs to create their own
piped commands, they can potentially gain access to any mailbox on your
Do you trust all of your domain admins enough to:
1) Not gain access to the contents of vpasswd files or the vpopmail.mysql
file on your system.
2) Not delete ~vpopmail/domains.
3) Not run anything in ~vpopmail/bin/ that they shouldn't.
Since the piped command runs as user vpopmail, this is a serious security
hole, and we won't open it back up.
