Preflight Mass-Checks By Mail

The email address automc /at/ spamassassin.zones.apache.org is used to run mass-checks by email.

If a mail arrives from a known good source to that address, containing a text/plain attachment, that attachment is extracted and saved, and the PreflightBuildBot signalled.

When those buildbot slaves run, they'll pick up the rules file, and check it with "spamassassin --lint". If it passes, it's used in the mass-check for that buildbot slave.

Results are visible immediately through the normal buildbot web UI. They are presented as 'freqs' output (as usual). They are also fed into the RuleQaApp.

Security

Because mail-submitted rules are OK, we have to be a little more careful than normal. For example, plugins are ignored in mail-submitted rules. Nothing is run if --lint fails. In addition, the preflight mass-check script runs with very paranoid ulimits, to trap CPU-load problems, and executes in a chroot jail with an unprivileged UID.

Adding Sources

A committer needs to edit build/automc/automc-by-mail and add the email address to the $ALLOWED_MAIL_PEOPLE regexp.
