SMTP Check

Check an SMTP server to ensure it is running and accepting connections according to RFC 821.

Settings:

Host Address: The hostname or IP address of the host running the SMTP server to be checked.

Port: The port SMTP is listening on, usually port 25.

Require TLS/SSL: If checked, a secure connection will be established using TLS/SSL.

Verify Text (Optional): The content returned can be checked for the presence of specific text. If not found, a "Content Error" will be generated. Note that the verification is case sensitive and the text must be found in the content exactly as it is entered here. To verify text using a regular expression, enter "regex:" followed by the expression.
