No. Content-Description is not machine parseable. It is recognized as a text file since that is the primary portion of the MIME type (which DOES have a defined syntax). michael ___ Michael Slusarz [slusarz at horde.org] Thanks Michael, so, is it able to give it a extension name (e.g. .txt , .html) for user to download? Because many users use MS Windows and will only say they cannot open it (just like this screenshot: http://eligrey.com/blog/wp-content/uploads/no_file_extension_open.png) No. Again, extensions are IRRELEVANT. They have nothing to do with how the browser/OS displays content. michael ___ Michael Slusarz [slus...@horde.org] -- imp mailing list Frequently Asked Questions: http://wiki.horde.org/FAQ To unsubscribe, mail: imp-unsubscr...@lists.horde.org

(e.g. HTML_Version_of_Message.html) No extension should be added unless that is how it is sent. Extension information is pretty much useless these days - even Windows doesn't use it anymore. What is more important is the *MIME type* we send when creating the download link. Any halfway recent OS will save that MIME part information in the file's metadata when saving.

Re: [imp] msg bigger than limit_inline_size, download without file extension name
Zitat von Nethub Online nethubonl...@gmail.com: Hi all, In imp/config/mime_drivers.php, there is a limit_inline_size for both 'plain' and 'html', according to its description above this limit, the user will only be able to download the part., it generate a link to let user download the part, however the file doesn't contains extension name (e.g. .html / .txt), for 'plain', the file name is Text (without extension name), for 'html', the file name is HTML_ (without extension name) Is it able to be with file extension name? Because normal end-users do not know how to open it (I believe).
