So I need to make sure I understand the mail integration.
I do not see an option to add mail (smtp) globally. Is it accurate to assume that the smtp server must be configured on EVERY alert??
At the moment, yes. I use a mail server of "mail.server.set.by.local.hosts.file"
Alternatively, add an alias for your mail server to your DNS system and use that in all your alerts.
This is a known change or feature request.
