buildbot questions

[Marko Käning]

> I suggest starting with something simple, like an email that says "step X failed. <link-to-build-run>", send it to the committer (which should be easy with buildbot's MailNotifier), and the maintainers(s) of all ports in that build run (harder, but possible). Under normal circumstances, each run/commit should cover a small number of related ports, so getting clever with filtering stdio output should be unnecessary.
Yep, simple is good.

I've found the section in the manual.

Just wondering how I could test the code without sending tons of emails to everyone around… :-)
Now that we're at it, does the buildbot machine need SMTP authentication or TLS to be able to send emails?
