Do NOT edit the sendmail.cf file. The correct way to do this is to make all changes in the /etc/mail/sendmail.mc file and then run the M4 macro. The instructions are at the top of this file. You will need to comment out (use dnl at the beginning of the lines) the lines near the bottom of the file that are stopping sendmail from listening for only the local host. Read the comments they're self explanatory. Once the M4 macro is run you need to restart sendmail by doing a service sendmail restart There are many reasons why you shouldn't make changes directly in sendmail.cf. Some changes are next to impossible to make manually, sendmail.cf may not work across releases of sendmail, all changes are made in one place and not lost, etc...
