The problem

It looks like Mojira uses the e-mail address bugs@mojang.com for all e-mails it sends, including for example password reset requests.
This is rather problematic because due to the amount of e-mails Mojira sends there is a tendency to just trash them all.

It would be really good if Mojira would use a separate e-mail for non-issue related information. This is apparently possible by setting the e-mail addresses for each project, see Configuring email notifications, but there are likely other ways as well.
