Distribution Lists

[dinux]

Is it possible to make it so that only people with email accounts ending in a specific domain name can send email to distribution lists?

[phoenix]

Yes, it is. Search the wiki for 'whitelisting'.

[dinux]

That search yielded no results. Any other ideas?

[phoenix]

Yes, search again. The word whitelisting will yield one page with the information you need. I assume you did go to the wiki link I posted?

This is the page that was returned to me and it says nothing about Distribution Lists and what I am trying to accomplish.

[phoenix]

That's the page you want. A distribution list is just another email address, follow the instructions in the section "Implementing Whitelist/Blacklist".
