<![CDATA[Mail app: expose munge_subject_threshold so users get a warning in the subject]]>Most of the people I host mail for are older volunteers. They never open the Spam folder, and mail scoring somewhere between 2 and 5 lands straight in their inbox, where they do click it. A visible warning in the subject line would help them a lot, because that is the one place every mail client shows, on a phone and in a preview pane alike.

The Haraka spamassassin plugin already supports exactly this: munge_subject_threshold together with subject_prefix. It is commented out in the plugin's own spamassassin.ini, and the mail app's config does not set it.

I cannot enable it myself in a way that survives. /app/code/haraka-config is part of the image, and the config Haraka actually runs with is rebuilt in /run/haraka on every start. Sieve is not an alternative here either, since editheader is not in this Pigeonhole build.

@girish Would you consider exposing those two settings, or simply shipping a sensible default? This one isn't about exposing SpamAssassin internals, it is a plain user-facing feature, and I suspect a lot of admins running mail for non-technical users would get something out of it.
