Our plesk spamassassin interface has stopped letting us learn more messages. Is there a maximum recomended number of learned messages? When we click on training we are shown Messages learned: 58818 as spam, 20955 as non-spam, 79773 total. Then when we select one message and click on "it's spam!" the page comes back almost instantly with Messages learned: 0 as spam, 0 as non-spam, 0 total. and no email messages listed. Might we have too many messages learned? Should we limit this with the bayes_expiry_max_db_size setting in /var/qmail/mailnames/name.com/name/.spamassassin ? Is something else going on?
