Spamassassin sa-learn Missing Messages

OS: 9.0 SA Version 2.55 (downloaded from SuSE archives) I fed sa-learn a single file with over 6000 messages but the output indicated it only accepted one message! I fed it a directory full of ham containing many thousands of messages but it only accepted 426! I tried creating a new spam.log file containing a few instances of know spam but it accepted non of them. My MTA is postfix 2.0 and I am invoking spamassassin via the anomy script file. There is, of course, no bayesian filtering taking place. I have scanned to SA docs and find nothing about mail file formats it works/doesn't work with. Any suggestions? Thank you, Lucky Leavell
