Splitting stuff doesn't remove messages from INBOX

[Matt Armstrong <matt@corp.phone.com>]

I'm running vanilla nnimap 0.129 with a vanilla (unpatched) pgnus
0.96.  I've got these split rules set up:

(setq gnus-secondary-select-methods
	'((nnimap "phcm" 
		  (nnimap-address "mail.phone.com"))))
	
(setq nnimap-split-inbox "INBOX")
(setq nnimap-split-rule
      '(("daemons"	"^To:.*foo@example.com")
	("misc"		"")))

Mail to foo@example.com does indeed get put into the "daemons" folder
and everything else gets put into "misc."  But, the messages also stay
in INBOX and get reprocessed every time I hit 'g'.  Each time I hit
'g', another copy of every message in INBOX gets put into the other
two folders.

Any suggestions on how I can get nnimap to delete the messages in
INBOX?
