Maybe check the call to ->walk_parts and ->body_str_set in lib/PublicInbox/Filter/RubyLang.pm. Also, historical versions of lib/PublicInbox/Filter.pm did a lot more with MIME parts replacment and removal: https://public-inbox.org/meta/8b78a44163743dcd4a235a1bc661471e29f091e6/s/ (but was too intrusive with DKIM) -- unsubscribe: meta+unsubscr...@public-inbox.org archive: https://public-inbox.org/meta/
