There are two popular models for MTA/MDAs. Run as root and drop priviledges to the receiving user or run under another uid/gid (like using gid mail) which then needs write access to all mailboxes. So depending on the security model of the MTAs you use you may or may not need the mail group being able to write into your mailboxes. I wouldn't change it, because if you don't seem to need it then no process is obviously running as gid mail. And in case you do switch to another MTA/MDA with a different security model you will not be surpised by mails not being delivered. -- Axel.Thimm at ATrpms.net
