I just started using Spamassasin 3.0 and am very impressed with it. Recently, on an old server that I just started to manage, I just found a spam infested mbox spool file with 15,000 spams in it. (52MB) Nobody had checked the mailbox in about 10 months.
Is it a good idea to run sa-learn on this giant spam mbox file on other servers that I get SA 3.0 installed on? Or no?
