Re: [CentOS] sendmail refusing incoming connections from outside [SOLVED]

https://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/ref-guide/s1-em...

Important The default sendmail.cf file does not allow Sendmail to accept network connections from any host other than the local computer. To configure Sendmail as a server for other clients, edit the /etc/mail/sendmail.mc file, and either change the address specified in the Addr= option of the DAEMON_OPTIONS directive from 127.0.0.1 to the IP address of an active network device or comment out the DAEMON_OPTIONS directive all together by placing dnl at the beginning of the line. When finished, regenerate /etc/mail/sendmail.cf by executing the following command:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
