Apple Mail has concealed attachments from me for the last time I hope! I noted a while ago that Apple Mail puts attachments inside the HTML half of the multipart/alternative container instead of outside in an outer multipart/mixed. If you've set up to prefer the plain text half mutt doesn't show you the attachment.
I've put a message-hook workaround on the COnfigTricks wiki page: http://wiki.mutt.org/?ConfigTricks but it feels a little special purpose. Suggestions? Cheers, -- Cameron Simpson <c...@zip.com.au> My motto is, 'Do it my way or watch your butt.' - Nathan Arizona
