Debugging and SMTP

Had wierd problems debugging the parts of the DNN store module that sends emails whilst accessing the internet from the Wifi at a hotel. In the end I think it could only be down to various SMTP ports being blocked.

I wasted a couple of hours trying to figure out where the problem was and finally gave up and downloaded DevNullSMTP - a java based 'dummy' SMTP server. It has a very simple gui and logs the emails it receives. It very quickly allowed me to establish that the code I was running was sending emails as I expected.

It could do with a few more features to be the perfect tool:
  • Basic authentication - at least accept them - ideally show the uid & pwd used
  • Decode base64 encoded messages to show the text real text of the email and subject
  • Accept SSL connections
but at least I can see that emails are being sent.

DevNullSMTP can be downloaded at: http://www.aboutmyip.com/AboutMyXApp/DevNullSmtp.jsp
