We're using v 1.17, PHP 8.0.x. All of our tickets are created through email fetching through OAuth.
It seems aliases on email mailboxes don't get routed properly.
Example:
We have an email mailbox called service1@domain.com. That is the primary email / logon ID. This mailbox also has an email alias of service2@domain.com.
Any email sent to service1 is fetched and placed in the properly department.
Any email sent to service 2 is fetched, however, it gets sent to the "default" department instead. No idea why.
There are no ticket filters in place. But I'm hoping ticket filters is the answer to get it routed properly, but haven't gotten any combination to work properly.
