Lessons in incompetence

I can't remember why now, but I recently tried to register for a service. I remember thinking it was really quite good. Well thought out, useful, and worth the risk that I'd end up getting spam, as I had with eMusic.

But when I tried to register, the box for my email address was clearly limited to 30 characters, and my email address has 31 characters.

So I thought I'd be helpful and send some feedback so they could improve their site, and I could use it:

    The original message was received at Thu,
    18 Jun 2009 08:43:09 -0400 from
    localhost.localdomain [127.0.0.1]

   ----- The following addresses had
         permanent fatal errors -----
    <feedback@myhappyplanet.com>
    (reason: 550-5.1.1 The email account
    that you tried to reach does not exist.
    ...

Way to go guys. prevent people from registering, and then prevent them from giving feedback. Good one. Life's too short to investigate their problems, I've tried to help, now I'm moving on.

How often have you tested your feedback mechanisms from external addresses?
