I'm running CentOS-7 on my home server, and have setup postfix + dovecot + spamassassin. Everything seems to be working fine, except that while spam is being marked as ***Spam***, it is ending up in ~/Maildir/cur/ .
I'd like to divert it to ~/Maildir/.Spam/ (where I can examine it with sa-learn). What is the simplest way to do this?
