I have set up a worker role with a startup task that is supposed to start the smtp-server and grant access for 127.0.0.1 to send emails through it.
see http://richardprodger.wordpress.com/2011/07/18/using-the-windows-smtp-server-in-azure/
When the instance is newly rebooted everything works like a charm but after a few hours I am no longer able to send emails.
Any Ideas as to what I can have missed in setup, I have followed the guide to the letter(three times) without any success...
I have searched and searched but been unable to find anything except that it is not recommended to use the built in smtp for blacklist reasons but since we are only using it to send error messages we don't really care about that.
