Bill H Posted November 7, 2008 Report Share Posted November 7, 2008 Here is are the three lines of Wireshark I receive when trying to use one particulat Email Server: Line_____Frame______Originate IP_____Destination IP__Service 2479___13.643247___18.104.22.168___22.214.171.124___SMTP___Response: 220 APPSERVER1.XXX.local SMTP service ready 2481___13.644240___126.96.36.199___188.8.131.52___SMTP___Command: EHLO localhost 2483___13.659967___184.108.40.206___220.127.116.11___SMTP___Response: 500 Syntax error, command unrecognized It looks like the Email Server does not understand the newer EHLO command. Under this condition the Email Client would then send the older HELO command. PBXNSIP does not send the HELLO command. Is this a bug or a missing condition?
