You can let spam.el detect spam in two ways, during split with
(: spam-split) or when you enter a group. The latter is called
autodetection.

The reason for this is that some groups might not be fed through your
splitrules, USENET news is an example of this. :-)

In case of a news group you can let spam.el detect spam for you in the
group and mark it with the $ sign. To do so you need to turn on the
autodetection for that group(s). To do so you set the group parameters
spam-autodetect and spam-autodetect-methods. I would recommend to use
G c to set those variables instead of G p since I don't know which
values are valid.

From what you write above (and which I have snipped), I think that you
want autodetection turned on for your INBOX.

Turn on autodetection for all your IMAP mailboxes, i.e. set the
aforementioned group parameters to sensible values by using
gnus-group-customize (G c) instead of G p.

Set for each group, or group of group, the spam-process-destination
group parameter to the group you want it to end up in. WARNING! DO NOT
include "nnimap+servername:" in spam-process-destination! That will be
added by spam.el.

If "this folder" is the spam folder, set spam-process-destination to
nil for the group (i.e. (spam-process-destination)) and mark all your
spam with M-d or S x while reading.

I would recommend you to set
 (spam-process
  ((spam spam-use-bogofilter)
   (ham spam-use-bogofilter)))
in a top level topic so you don't have to set it for each group.

That's the way spam.el is designed.

You're not afraid of loops?

The reason for the problem might be that you split it back to the
source. Sounds strange to me, but I haven't looked into the IMAP stuff.
