In Gnus, with the cursor on the body of a message, you can pipe the
patch-in-body using the `|' shortcut or M-x gnus-summary-pipe-output and
then giving it the command "git am -s" as Ludovic pointed out some time
ago. It works the same if you place the cursor on a MIME (attachment)
object. You can also apply multiple patches in a row by giving it a
prefix argument (e.g. C-u N |) to apply N patches from N messages
(haven't tried that one yet but it's documented, see C-h f
gnus-summary-pipe-output).

I intend to script this method in Elisp so that would deal with both
types of patches (in-body/as-attachment) transparently but haven't
gotten around it just yet. I packaged the very old emacs-dvc thinking it
could help in doing that but it doesn't, so haven't bothered releasing
it.

I can highly recommend Gnus to get some hold of high mailing list
traffic. Expiry is a nifty way to storm through the mails, and there's
always the last resort 'c' catchup that will put you back on top of
things after coming back from a long weekend.
