Important information to config file handling:

==============================================

The latest version of the sendmail package for Red Hat Linux now uses the new

and recommended way of separating sendmail into two applications, one for

email delivery, the other for email reception. The former doesn't need to run

as root and uses a separate configuration file, called /etc/mail/submit.cf. The

later only provides email reception functionalty and, as before, uses

/etc/mail/sendmail.cf as it's configuration file.

The resons for spliting sendmail into two separate applications and how to use 

it is described in more detail in /usr/share/doc/sendmail/SECURITY.

!Note!

======

New in the latest package now is also that the configuration files will be

automatically updated after a restart if the corresponding mc files in

/etc/mail have been modified so changes done to the sendmail.cf and submit.cf

file will be lost if not done in the respective sendmail.mc and submit.mc

files, too.
