Telnet SMTP connection test

Testing the SMTPG connection to your mail server need not be difficult. This is what I usually do to test my mail servers’ SMTP status.

Telnet SMTP connection test

Open the command prompt. Use the following command.
telnet <smtp server’s name or IP Address> 25

You will the receive the SMTP server’s welcome screen.

Enter word helo . This will initiate the session.

Introduce yourself to the SMTP server by using the mail from: command.
mail from: <your email address on the domain>

Then, specify where you want to send the email to by using the rcpt to: command.
rcpt to: <receipient’s email address>

Next is to enter some message. Use the data command.

After completing your message, type “.” on a line by itself and enter. As per the diagram below.

The SMTP mail server will then generate the mail id and send the email. To end the session, type quit.

That’s how simple it is to troubleshoot if your mail server is serving your emails or not.

Winpooch test result

After trying it up in a few high end machines (HP 7700 - Core 2 Duo 2.13Ghz with 4GB DDR2 866Mhz RAM), I noticed that after installation of Winpooch and Clamwin, the machines tend to lag and applications starts to slow down. After removing the software, the machines went back to its super fast operation. Not sure if this is caused by Winpooch, but I will do further test.

Winpooch - An open source Anti Spyware and Antivirus

While searching for alternative anti-spyware and anti-virus, I stumble upon a promising GNU GPL licensed windows watchdog - the Winpooch. Some features listed on their website includes:-

  • Description: detection of spywares and trojans. It becomes an anti virus if associated with ClamWin
  • Development Status: open source project in progess
  • Environment: Win32 (MS Windows)
  • License: GNU General Public License (GPL)
  • Natural Language: English, French, Italian, Polish
  • Operating System: 32-bit MS Windows (NT/2000/XP)
  • Programming Language: C

The interesting part is, it works together with ClamWin to make it real-time virus scanner. Will this actually slow down the workstations?

Will be testing it out on our computer labs. Stay tune for the results.
