cannot telnet port 25 from other hosts

[Snehangshu Karmakar]

  Hi
Find a entry DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
and add dnl in front to coment it from the file sendmail.mc and use m4 macro to recreate sendmail.cf file.
m4 sendmail.mc < sendmail.cf 

Then restart the sendmail service.
