Hi, list.

Our user reported a strange issue: sent mail by roundcube 0.2/0.2.1/svn version, opened in MS Outlook, the attachment filename were changed:

 Original |  Changed
 file.xls =>  file.doc
 file.doc =>  file.dat

Is it a roundcube issue or Outlook issue?

Check the message source and you'll know.

Part of message source:

Composed by roundcube 0.2-stable:

Content-Transfer-Encoding: base64 Content-Type: application/msword; name="Testik.xls"; charset="UTF-8" Content-Disposition: attachment; filename="Testik.xls"

another:

another:

It seems roundcube 0.2.1-stable detects the correct mimetype.
