Hello Everyone -

I am getting an error message that I can't figure out how to fix. What happens is that someone tries to sign up on any site on my server and they get this error:

Sorry! There was an error: Can't send mail because of an unexpected server response. I said "RCPT TO: " and the server replied "553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)".

The member creates in the database just fine and they can go in and log in. This just looks like a problem with the server sending the email. Any idea of where to start to fix this?

Thanks,

Ryan
