Sending smtp mail via telnet (posted: 9-27-04 10:13 PM)
Sometimes sending an email message using a telnet command line interface can be a handy troubleshooting tool. You can verify that a server's SMTP service is functioning, test to see if a server allows mail relay, and sometimes even see the server software and version number. Here are the commands to do it [hit the "Enter" key after each command to get a prompt for the next one] :
telnet smtp_server_name 25
helo smtp_server_name
mail from: me@mydomain.com
rcpt to: you@yourdomain.com
data
type_your_email_message_body_here
(When you finish typing your e-mail message above, press [ENTER], then a '.', and then press [ENTER] again.)
quit
