SMTP Prober

SMTP Prober will certainly be used by developers to test software and websites for proper SMTP server setup.

SMTP Prober is useful when creating websites in languages such as PHP, which will send a confirmation or notification email with the SMTP settings on the host server. If your PHP code returns with an error message, such as "5.7.1 Could not forward to ...", you can use the test tool to check if you have the correct code configuration settings.

If necessary, you can save the settings. The settings are saved in an INI file named default.ini. This file is saved and run from the same folder where SMTPProber.exe is located.
