When I send an attachment with accent name like questionário.doc, the evolution 1.4.6 or KMail uses the follow headers to the SMTP Server: Content-Disposition: attachment; filename*=iso-8859-1''question%E1rio%2Edoc Content-Type: application/msword; name*=iso-8859-1''question%E1rio%2Edoc The SMTP server lost the file name and convert the to an ATTXXXXX.DAT file name. If a send a non accent filename none charset is used and the original filename is preserved. Does Anyone know where to configure attachment charset in KDE, I've just found message body charset in KMail and Evolution ?
