Allow only specific domain to email a distribution group
I figured out a way. Using a mail flow rule where the header contains "To" of the distribution group. And have it block those messages, and an exception of the domains to allow.
VasilMichev , thanks for the clue.
VasilMichev - I already tried a mail-flow rule and it didn't work; and then I found the reason why:
"Note - If the Mail flow rule is configured to check for the recipient where the recipient is a distribution group, the rule won't be matched. When the message is sent to a distribution group, the group will be resolved to distinct users of that group before reaching Mail flow rules and instead, will check every member of a group."

Here is a screenshot of the rule
- I don't see "includes any of these recipients in the To or Cc box" condition. I only see options for word match or text pattern and I've tried both.
