This adds the following features:

1) Command line arg -m4:

  /sbin/conf.d/SuSEconfig.sendmail -m4 will write the sendmail-m4 configuration
  to stdout. (Running this through m4 will result in /etc/sendmail.cf.)
  
  This patch should be included in SuSE 8.0.  VK 22 Apr
  It's not - I have not ported it from SuSE 7.3 for now.  VK 13 Jun 02

2) DNS RBL lookups:

  Add the feature of DNS RBL lookups to SuSEconfig, which can be
  configured via SENDMAIL_DNSRBL in /etc/rc.config.d/sendmail.rc.config

  VK 23 Mar; 13 Jun 2002

3) Masquerade exceptions:

  Domains listed here will not be masqueraded to FROM_HEADER for outgoing mails.
  Configured via MASQUERADE_EXCEPTIONS in /etc/rc.config.d/sendmail.rc.config
  
  VK 23 Mar; 13 Jun 2002

  This functionality is included in SuSE 8.0 and can be set up with yast2, or
  by adding domains for which mail should be received to SENDMAIL_LOCALHOST and
  those domains only which should be masqueraded to MASQUERADE_DOMAINS in
  /etc/sysconfig/sendmail.
  
  VK 9 Jul 2002

4) Trusted users

  Trusted users (who can change their name when sending mail) can be added via
  SENDMAIL_TRUSTEDUSERS in /etc/sysconfig/sendmail
