tlug: Once again Procmail setup

[Dennis McMurchy <denismcm@example.com>]

  Sorry to have bothered you all.  Reading a little further in the
same mini-faq I mentioned reveals the real source of the problem:

Upgrading to 3.12/3.13/3.14 breaks Procmail on systems with group-writable home
directories (e.g. Red Hat Linux) 
   This is known to the Red Hat folks, and a fixed RPM is apparently in
the works. See    http://developer.redhat.com/bugzilla/show%5Fbug.cgi?id
=2242     (Apparently this can also bite when upgrading to Red Hat 6
from an earlier version.)     This is not a problem if Procmail was
compiled correctly. For example, Debian has    group-per-user, too, but
the current .deb package was correctly compiled to reflect this.   
The general explanation is that Procmail was tweaked to be more
paranoid about security    issues, and will not accept an rc file if it
is group-writable. This is a non-issue on systems    where the only
member of the group will be the user herself; for those systems, there
is a    GROUP_PER_USER switch in config.h which needs to be enabled
before compiling    Procmail. (This was not done for Red Hat's
procmail-3.13-1 RPM but should    hopefully be fixed in the next. An
independently fixed RPM seems to be available at    http://cs.wilpaterso
n.edu/~scottw/shebang/ but this appears not to be "official".)     One
of the popular error messages returned in bounces in this situation
seems to be    "Service unavailable" which is not very helpful. (See
the smrsh question below,    too.)  

  Gotta love that RedHat, eh?
