Troubleshooting Mail Delivery
SMTP Probe
The SMTP (Simple Mail Transport Protocol) Probe is used to test email connectivity with a remote
SMTP server. This allows you to verify that the SMTP server is responding to connection requests
and returning a valid response.
In the SMTP Probe screen, you must enter the destination SMTP server, the envelope header fields
for the sender and recipient (MAIL FROM and RCPT TO), the HELO identifier, and the message
data.
Click the Send Message button to send the test message to the destination SMTP server.
The server should come back with a response.
• SMTP Server — Enter the domain name of the destination SMTP server that you want to test.
• Envelope-from (MAIL FROM) — The MAIL FROM part of the email message identifies the
sender. Enter an email address indicating the sender of the message.
• Envelope-to (RCPT TO) — The RCPT TO part of the email message identifies the recipient
of the email. Enter an email address indicating the intended recipient of the message.
• HELO — The HELO parameter is used to identify the SMTP Client to the SMTP Server. You
can enter any value here, but the sending domain name of the server is usually specified.
• Message to Send (DATA Command) — This contains the actual test message data. You can
enter an optional subject to ensure a blank subject field is not sent.
The response field will show the result of the SMTP diagnostic probe, including the response for
each SMTP command sent:
