## *** DEFAULT SETTINGS FOR THE ATTACHMENTS PATCH ***
##

##
## Please see the manual (section "attachments")  for detailed
## documentation of the "attachments" command.
##
## Removing a pattern from a list removes that pattern literally. It
## does not remove any type matching the pattern.
##
##  attachments   +A */.*
##  attachments   +A image/jpeg
##  unattachments +A */.*
##
## This leaves "attached" image/jpeg files on the allowed attachments
## list. It does not remove all items, as you might expect, because the
## second */.* is not a matching expression at this time.
##
## Remember: "unattachments" only undoes what "attachments" has done!
## It does not trigger any matching on actual messages.

## Qualify any MIME part with an "attachment" disposition, EXCEPT for
## text/x-vcard and application/pgp parts. (PGP parts are already known
## to mutt, and can be searched for with ~g, ~G, and ~k.)
##
## I've added x-pkcs7 to this, since it functions (for S/MIME)
## analogously to PGP signature attachments. S/MIME isn't supported
## in a stock mutt build, but we can still treat it specially here.
##
attachments   +A */.*
attachments   -A text/x-vcard application/pgp.*
attachments   -A application/x-pkcs7-.*

## Discount all MIME parts with an "inline" disposition, unless they're
## text/plain. (Why inline a text/plain part unless it's external to the
## message flow?)
##
attachments   +I text/plain
  
## These two lines make Mutt qualify MIME containers.  (So, for example,
## a message/rfc822 forward will count as an attachment.)  The first
## line is unnecessary if you already have "attach-allow */.*", of
## course.  These are off by default!  The MIME elements contained
## within a message/* or multipart/* are still examined, even if the
## containers themselves don't qualify.
##
#attachments  +A message/.* multipart/.*
#attachments  +I message/.* multipart/.*

## You probably don't really care to know about deleted attachments.
attachments   -A message/external-body
attachments   -I message/external-body
