Would it be possible to skip sending mail on hardware/OS/out-of-disk 

I imagine this is just a matter of checking the process exit code from 
the build system: 0 for success, 1 for build failure that sends 
notifications, everything else is an admin problem.

If the script in use has no code owner, I'll appreciate a pointer to 
what's sending the mails and I'll see if someone can look into it and 
submit a patch.

We should be more proactive and disable noisy build servers until a 
technical solution is available rather than the other way round, given 
how they drown out real problems.
