Should client side splitting via nnimap-split-rule be working with the
new nnimap?  Mine is not.  I'm happy to help debug in whatever way is
most useful.

Currently all new messages on the "dc" server stay in nnimap+dc:INBOX,
but I expect them to be sorted according to the rules in
nnimap-split-fancy.

#v+
(setq nnimap-split-inbox '("INBOX")
      nnimap-split-predicate "UNDELETED"
      nnimap-split-rule '(("dc" ("INBOX" nnimap-split-fancy)))
      nnimap-split-fancy
      '("X-Spam-Flag" "YES.*" "mail.spam"))
#v-

Thanks for any tips,
/au
