The release notes state: By default, sendmail does not accept network
connections from any host other than the local computer.
To fix this problem:
Edit the file: /etc/mail/sendmail.mc
Change the local address defined in the DAEMON_OPTIONS line(127.0.0.1)to
0.0.0.0
so that it accepts from all IPs.
You will then need to regenerate /etc/sendmail.cf by running:
m4 /etc/mail/sendmail.mc > /etc/sendmail.cf
