My asp just stopped working

I haven't changed anything

[Blelisa]

Hello everyone,
I just received an email from a friend of mine who I designed his site for him. I made a register page that asks for general information that gets logged into a sql database. For some reason it stopped working. Now If you try to register you get this error message.

Error encountered: 554 : Recipient address rejected: Access denied

I have not changed anything in months. Anyone have any idea what it could be?

Thanks in advance for any help

Are you using CDONTS or a 3rd party emailer?

Yeah...sounds like something is going on with your emailer. I'm guessing your users register and a confirmation email is sent to them?

When someone registers it emails the contact at the company to let them know that someone has registered. I have contacted the web/email hoster to see what has changed. Thanks for your help!

Here is a shot in the dark but I recently experienced something similar and I looked at my control panel and I maxed out my space on my account (not the bandwidth but the space for files). So I would suggest checking how much/if you still have space. Good luck either way. :)
