I personally don't trust so much SpamAssassin but this is just me and you appear to be happy with the results from SpamAssassin and you obviously trust them. When I started with statistical filtering I was under the impression that pre-training much will help me to catch more spam. But to be honest: With the right tokenizer and pvalue, DSPAM is learning very fast. A hand full of corrections help you to get above 99%. If you want to pre-train your DSPAM, then have a look at this thread: http://forums.gentoo.org/viewtopic-t-580207-highlight-.html > I've added the train-spam and train-ham aliases to /etc/postfix/aliases > and run newaliases. > > I assume I'll need to add a row in dspam_virtual_uids for 'globaluser'? > What about train-spam and train-ham?
