I don't believe this is a mailscanner issue. I also have found
sa-learn not learning anything over a certain size. It's been a while
(a month) since I've seen large spam so I never bothered.
mailhost# ls -l notspam.msg

mailhost# sa-learn --ham --username=duane@virtualnetwork.com notspam.msg

If I chop everything out except the message headers:
mailhost# sa-learn --ham --username=duane@virtualnetwork.com notspam.msg
Learned tokens from 1 message(s) (1 message(s) examined)
