SMTPTester

One of the challenges I’ve had is testing SMTP server configuration’s supplied by our clients. Often there are problems with certificate validity or various other security settings. I wrote a simple tool to allow for testing/debugging from the command line. You can find the project at SMTPTester and the first version can be downloaded at SMTPTester - 0.1.0.

It allows you to send test messages, dump the certificate’s of the SMTP server to disk and optionally ignore certificate errors. There is detailed error logging available in verbose mode.
