Maintainers without a Bugzilla login are not notified about issues filed for their ports. 1) we may want to create a login automatically for them on the first bug submission and inform them about it 2) we may want to inform them (without creating a login) via the auto assigner
I'm +1 on (2). The idea of implicitly created ghost accounts is unappealing.
Maintainers without a Bugzilla login are notified via mail now.
