WordPress MU

Hi =)

We have a virtual dedicated server, but the email accounts
we have setup at the server work using the service provided by everyone.net

These email accounts are free.

When a new Blog is created, WordPress MU will send the password to the user's email, however, it will not send it if the user has an email account at our own domain.

Does anyone know of this issue ?

Thank you in advance =)

Server spam protection, I wildly guess.
