Re: [courier-users] sendmail works with root but not users (#1

This is a MIME GnuPG-signed message. If you see this text, it means that
your E-mail or Usenet software does not support MIME signed messages.
The Internet standard for MIME PGP messages, RFC 2015, was published in 1996.
To open this message correctly you will need to install E-mail or Usenet
software that supports modern Internet standards.

Something is screwing up the permissions of files on your box. Nothing to
do with Courier.

There are other setuid and setgid programs in Courier. Chances are that
they got screwed up too.

Find out what's doing this, and TURN THIS BLOODY THING OFF.
