Yup, in nnimap 0.93. The syntax will be like the nnmail syntax, eg:

(setq nnimap-split-rule '(
	...
	("INBOX.\\1"                  "^Sender: owner-\\([^@]+\\)@")
	...
	))

You can also have elisp functions instead of the regexp (but then you
can't use the \\1 syntax, of course).

I think the nnimap split stuff is as capable as the nnmail right now,
except for fancy splitting. Since I don't use fancy splitting I won't
add that myself, but if someone feel the need for it I'm always
accepting patches.

Well, a backend-independent mail splitter would be very neat, but that
seem to require lots of changes to Gnus.
