Resolution
Simple way to test SMTP email for testing purposes.
- Make sure telnet is turned ON in Windows. (If not, go to Control Panel > Programs > Turn Windows Features On or Off > turn ON the Telnet Client.)
- Open a command prompt and type telnet domain name (or IP address) and port.
telnet 10.169.9.10 25 - Type HELO and identify the sending system
helo MyPCName - Type mail from: followed by an email address
mail from: user@tac.com - Type rcpt to: followed by destination address. (NOTE: must be an email account in the mail server)
rcpt to: user@3indq.com - Type data then ENTER key
- Type a message
- Type . (period) then ENTER to end
NOTE: Type slowly and if you mistype something hit enter and after the error re-type the line. Using backup space appears to work but it doesn't.
NOTE:
- Make sure Telnet server is installed on the SMTP server.
- Make sure Telnet service is enabled/running on the SMTP server
