  • # cd /usr/share/sendmail/cf/cf
  • Edit sendmail-slackware.mc :
    • Add the line FEATURE(`no_default_msa')dnl to the end of the FEATURE block
    • Add the line DAEMON_OPTIONS(`NAME=NoMTA4,Family=inet,Addr=127.0.0.1')dnl right before the MAILER lines
  • # m4 sendmail-slackware.mc > /etc/mail/sendmail.cf
  • Add something like
root:           user
user:           user@example.org
to /etc/mail/aliases; then run the command newaliases
  • # /etc/rc.d/rc.sendmail restart
  • Make sure that the fqdn-hostname is in the DNS (has an A record) and is whitelisted in the inbound smtp server for example.org
