I try to send an email to email@example.com, using one of my email accounts I get it bounced back instantly with an "invalid recipient" message.
The mail server is mail.bigpond.com, if I try any other of my email accounts with different isp's it works fine.
Why might this be happening?
Thanks for any help.
