Hey there,

I have a domain with tons of addon domains under it. Most of them receive thousands of email spams daily, and I need to control it.

Here is an example:
cheaptravel.maindomain.com

The only email address I need to work here is:
webmaster@cheaptravel.com
support@cheaptravel.com

Anything else to cheaptravel.com I want to bounce. What do I need to do here to make the above work?

I've tried the forwarding option, but that ONLY seems to works for:
webmaster@cheaptravel.maindomain.com. It doesn't seem to have any affect on the main cheaptravel.com domain.

Most the other addon domains I do not want any email to work at all. But the :fail: and :blackhole: options only seem to work with the domain.maindomain.com addresses, and not the main domain.com addresses.

Thanks in advance. I really need to get in control of this email!
