Uhm, nope... ;-)

Currently, attachments are always downloaded, regardless of trhe
Content-Disposition header.

btw: What you describe even does not make sense for files, that cannot
be previewed...


I personally would like, to *not* retrieve attachments by option --
regardless of Content-Disposition header. I don't like it, that someone
else can force me to be in-operative for a long time, just by sending a
huge attachment.

The IMAP rewrite is due to what date?? ;-)
