SMTP - How to verify your connection and parameters (TSL/SSL) with TELNET ?
Telnet
Below, you can find all the command that you must tape in the telnet windows.
If you don't use a SSL smtp, you can ommit the lines :
AUTH LOGIN bG9naW4= <-- login cGFzc3dvcmQ= <-- password
ehlo nico AUTH LOGIN bG9naW4= <-- login cGFzc3dvcmQ= <-- password MAIL FROM: nicolas.gerard@newfrontiers.com RCPT TO: gerardnico@gmail.com DATA This a big big test . QUIT
The Smtp Server will always respond with a message.
If you do a mistake when you tape a command and then you go back to correct it, you will have in anyway an error message.
QUIT 500 5.5.1 Command unrecognized: "QUIT"
This message is not true, the command QUIT exist but if you have done a mistake as for instance if you have written QUIY, you correct it and you valid, you will have this error.
Open a command dos and launch telnet for the smtp server smtp.xs4all.nl on the port 587
Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:\Documents and Settings\Nicolas>telnet smtp.xs4all.nl 587
The server smtp must answer :
220 smtp-vbr15.xs4all.nl ESMTP Sendmail 8.13.8/8.13.8; Sun, 26 Apr 2009 14:17:28 +0200 (CEST)
And you can begin to talk :
