Is SA more effective than popfile? And can you manually train it (if you have

I set up popfile on clients' computers to help them both with spam and
categorization, but it's not the best solution to spam.
1. Yes. It has access to more tests. Popfile is only (only?) a Bayes
analysis filter. SpamAsssassin uses a wide variety of tests, some
coming with the system, some self-made, and some from places like Rules
Emporium.
2. Yes, but root access is not required. I set up IMAP folders
"should-be-spam" and "should-be-ham" for each user and have them drag
messages that are misclassified into them. A scheduled job (run as root)
executes sa-learn to update Bayes filters.
For example:
sa-learn --spam --mbox /home/*/mail/should-be-spam
sa-learn --ham --mbox /home/*/mail/should-be-ham
