Re: [dspam-users] Merged groups and classification groups

Hi Jeff,

So if I wanted to merge any future training data for, say, foo and bar
into globaluser so that I can then keep globaluser up to date without
having to go in and manually feed it mail, and use it as a
classification source, I could do:

globaluser:merged:foo,bar
global:classification:*globaluser

And if I want to give globaluser the training data accumulated in the
past by foo and bar, I'd use dspam_merge to merge those dictionaries
together?

Regards,

Adrian
