Created attachment 1421 [details] patch to pgpmime.c in git I attach a patch to remove "Content-Disposition: attachment" from PGP/MIME signed messages. This prevents misleading the recipient from thinking that there is a purpose to the attached signature file. This patch causes no change in functionality - all PGP/MIME signing works as before. Tested on latest stable versions of Claws Mail, Thunderbird, Mutt, Evolution, Outlook 2007, Outlook 2010, Outlook 2013. Patch submitted as unified diff against current GIT. The patch is licensed under the same license as Claws Mail.
applied with a modification. Thanks!
