when downloading a emil source,the filename suffix will be msg.i think it should be change to eml.
.msg is the microsoft outlook's format,it is associated with Microsoft Outlook
.eml is the rfc822 emial format.by defulat ,it is associated with Outlook Express
123 else if ($type1 == 'rfc822' && $type0 == 'message')
124 $suffix = 'eml';
thank you very much
