Forward email only from local domain

Hello,
Can I restrict forwarding emails only from the local domain?
Example: I can send emails to all@mydomayn.com only from the mailboxes  *@mydomain.com.

if im not wrong you can create all@yourdomain.tld mail box
then you set filter inside the mail box


with filter
from : @yourdomain.tld forward to user1@yourdomain.tld user2@yourdomain.tld userxx@yourdomain.tld

Not working...I try different ways. Make a filter that like you say but not forward messages. Filters work only for the mailbox (all@mydomain.com), if I make forward or add the filter to redirect messages nothing happens.

yes.. it only WILL fwd all@domain.tld to other mail

actually what you want to do ?
mailing list ?

Yes! The email all@domain.com is a mail list with all mailboxes in the company. We use it only for internal messages but lately, we have received many fishing emails. For that, I wanted to restrict which mailboxes can send emails to it.
