As has been clarified, this is not your issue. No way it will skip

Please check the Conf docs. If you don't have any need to specifically
set them, just leave out all those options and let the magic work.

That's 25 kByte! Yes, that is your problem. Any mail larger than that
will NOT be processed by SA.
The default has been 500 kByte for a long time, and was 250 kByte
before. That line looks like an obvious *typo* to me. An ancient one.

100 kByte, still really low.

man spamc. Without that procmail condition, spamc simply will return any
messages exceeding the (default) size limit unprocessed. Using an
explicit limit here will spare the unnecessary filter, since spamc won't
even be called.
I recommend setting it to the limit you want enforced -- and hence
setting it to 500 kByte if you don't want to change the spamc default.
