When selecting a Mail Transport for an alert rule, I can add a single Mail Transport and then Save.
When I go back to any rule and try and change the Mail Transport, I delete the old one, select the new one. Only the new one is visible. Click Save.
When I go back to that same alert rule, the old and the new mail transports are both visible.
I can repeat the process and add a third mail transport and then when I go back, all three are there. etc. etc.
I took a look at the alert_transport_map in the DB, and it just appends a new ID with the rule_id so it just keeps appending rather then pruning/modifying the table.
