the Mail app for iOS is more faithful to the MIME specification. if you send an HTML mail with the content-type multipart/related, attachments are rendered inline where the HTML body references it by its content-id.
if you do not reference your attachments in your HTML by their content-id, they will effectively be hidden on iOS. by contrast, if you specify the content-type multipart/mixed, attachments are considered unrelated and rendered after the HTML body. > 2019/06/05 2:35、macjimbo via 4D_Tech <4d_tech@lists.4d.com>のメール: > > At the receiving end, the attachment appears without a hitch on a desktop > client like Apple Mail, but on a mobile iOS device there is no sign of the > attachment at all. It just isn't there. ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
