SA Bugzilla – Bug 2208
SpamAssassin does not recognize bayes size changes

Changing the 2 values, "bayes_expiry_min_db_size" and/or "bayes_expiry_scan_count" in /etc/mail/spamassassin/local.cf appears to have no effect. Expiration still occurs at 5000 and the DB does not increase in size.
those two options no longer exist in 2.60, which will be the next release of SA. so closing this bug as wontfix (although I haven't confirmed that it occurs).
