In the last months and years, the default `mime_types.conf` of rspamd has changed and it might be also useful to make some adjustments to the weight of certain file extensions. This PR is removing all file extensions from `mime_types.conf` which are already in rspamd's default configuration at [rspamd/src/plugins/lua/mime_types.lua](https://github.com/rspamd/rspamd/blob/master/src/plugins/lua/mime_types.lua). If file extension is not present or has a different score compared to rspamd default, it is still in the list. There are also a few major differences to certain file extensions, which might be useful to discuss and carefully adjust. For example, `.exe` files are rated very 'badly' due to high chance of being malicious, so are other extensions like `bat`, `cmd`, etc. Current suggestion: ```lua # Extensions that are treated as 'bad' # Number is score multiply factor bad_extensions = { apk = 4, appx = 4, appxbundle = 4, bat = 8, cab = 20, cmd = 8, com = 20, diagcfg = 4, diagpack = 4, dmg = 8, ex = 20, ex_ = 20, exe = 20, img = 4, jar = 8, jnlp = 8, js = 8, jse = 8, lnk = 20, mjs = 8, msi = 4, msix = 4, msixbundle = 4, ps1 = 8, scr = 20, sct = 20, vb = 20, vbe = 20, vbs = 20, vhd = 4, py = 4, reg = 8, scf = 8, vhdx = 4, }; # Extensions that are particularly penalized for archives bad_archive_extensions = { pptx = 0.5, docx = 0.5, xlsx = 0.5, pdf = 1.0, jar = 12, jnlp = 12, bat = 12, cmd = 12, }; # Used to detect another archive in archive archive_extensions = { tar = 1, ['tar.gz'] = 1, }; ``` **As a important reminder**: For all remaining and additional file extensions and score weights, please check above default rspamd configuration! |
