Hi
I just got an message from twitter "
"Is your email address active?
We've tried to send emails to 'info

mydomain.com', but they are not getting delivered, possibly because your email address is no longer valid. Click here to update your email settings, or click here to try sending messages to your email address again."
I send a testing e-mail using my gmail to the
info
mydomain.com and it works, but why twitter and other forums that i sign up with can't send it to my email?
