In main.inc.php, the explanation is different:
// Encoding of long/non-ascii attachment names: // 0 - Full RFC 2231 compatible // 1 - RFC 2047 for 'name' and RFC 2231 for 'filename' parameter (Thunderbird's default) // 2 - Full 2047 compatible $rcmail_config['mime_param_folding'] = 0;
So what is true? Is "RFC 2047/2231" Outlook's (as the UI says) or Thunderbird's (as the config says) default? And what is the best option in terms of backwards compatibility...?
Both are true. It just Thunderbird's default is what works with Outlook ;) The best is 1.
Furthermore, this really shouldn't be a user-configurable option. RFC 2047/2231 are way too complex and hard to understand for an end-user. This should be set server-side only. I'm wondering how this option could make it into the UI.
There was once a "advanced" switch, and this option was hidden by default. Then the switch disapeared. However, Thomas added a ticket with feature request to get back the switch. So, in the future we'll have some set of advanced options, hidden by default. For now, as with every option, it can be hidden using dont_override setting.
