Hi,
I've been a happy Roundcube user since 2008 which, now that I look it up, seems to be almost the beginning. Thanks for a great tool.
Recently we've discovered a need to provide some kind of warning when the user receives an eMail with an executable or archive (zip, tar, dmg) attachment.
We use these kinds of attachments legitimately in our day-to-day work so don't want to filter them at the mail gateway, but there's a compliance need to tell the user that it may be dangerous.
I've had a look in the config as well as the plugin list and Google'd a bit but can't find anything that might be suitable.
I saw something about a warning that comes up when the extension and the mime-type don't match but that doesn't seem to be what I'm looking for and I can't work out if it can be configured and, if so, how to configure it to do what I want.
Can anyone point me at a config option, plugin or something else that will allow us to display a warning when an eMail contains a "potentially dangerous" attachment?
Thanks!
Best wishes, @ndy
