Sendmail on Solaris 9: could not send or receive email - port 25 is blocked
I have setup my Solaris 9 machine recently. I could send and receive email from localhost to other unix accounts but could not send and receive email to or from outside. I tried "telnet servername.com 25" from outside and it did not connect to email server but I could "telnet localhost 25" from inside. Could some one tell me what I need to do?
