Good guess: I indeed set show_trimmed_content to true because the reply trimmer code frequently trims more than it should. Not just in the imported mbox, it also happened daily with replies by email. Although it should be possible to improve the trimmer it seemed like an uphill battle. People using mail will always (i) send weirdly formatted emails for whatever reason, (ii) expect them to be displayed in full.
There indeed are other issues in the import: it is far from perfect. Although I’d be happy to discuss them, they are not an immediate concern.
Since it looks like I did not miss an option in the import that would obfuscate emails there apparently are two options left:
- Globally replace content in the posts with something like s/{email_regexp}/obfuscated/
- Find/write a plugin that obfuscate displayed content (HTML converter ?) with s/{email_regexp}/obfuscated/
Or… I’m going in the wrong direction?
