Bugzilla Bug 841

For a non-root user, postdrop fails with

"warning: mail_queue_enter: create file maildrop/###.###: Permission denied"

where, ###.### is some number.  The reason is that postfix isn't installed with 
setgid (install.cf), so postdrop runs with the permissions of the user who runs 
it (postdrop is called by postfix's sendmail replacement, which is called by 
mail programs like mutt).  But /var/spool/postfix/maildrop is installed with 
user/group postfix/postdrop and isn't world-writable.  Postdrop needs to write 
to that directory, so if setgid isn't set in the postfix install/build, which 
appears to not be, /var/spool/postfix/maildrop should be world-writable (the 
Mandrake postfix install does this).  However, the better answer is to set 
setgid on the postfix install.

The URL above has more info: Scroll down to "Protecting your maildrop 
directory".

latest postfix fixes this problem .. thanks woodchip :)
