I actually receive mail in an account different account. When training, I thought I could just run sa-learn as root and get the desired affect. I’ve run it as the correct user and I’ve at least of couple of duplicate messages correctly labeled as spam.

Bayes needs sufficient examples of both spam and ham in order to make a decision. The default minimum is 200 of each. There's also the common error of training a different bayes database than the one that SA is using when it scans mail.

Improve spam hit rate
I have these messages in a paste: http://pastebin.com/jNQfRerx http://pastebin.com/jNQfRerx. They were received about 1 1/2 hours apart. After I received the first one, I ran sudo sa-learn —spam /path/to/mail/folder against it and then sudo sa-learn —sync. spamassasin reported that it ‘learned tokens from 1 message…’ I received the second message, but it was not marked as spam, even though, at least as far as I can see, the messages are identical. All the way down to the low contrast ‘hidden’ text. I’m seeing a lot of this lately, although sometimes, the messages come from different domains (reverse lookups are always ok). My server is Ubuntu linux 14.04. What can I do to improve the detection rate? I’m running sa 3.4.0 which is invoked via postfix in master.cf: smtpinetn - - - - smtpd -vvv -o content_filter=spamassassin sa-update is run via a cron job daily and it last ran early this morning, so its rules should be up to date. So, any ideas? Thanks
