I've got that problem:
MyName@example_one.com is my first address.
On my second domain i have the alias:
Everyone with addresses ending with example_one.com can find me in the global address list.
But on the other domain nobody can find me. For example:
user1@example_two.com can find user2@example_two.com in GAL, but user1@exampe_two.com cannot find MyName@exampe_two.com (my alias).
What can i do?
