I'm fortunate in that the Domino mangement will be performed by someone who's particularly good at Notes development. I need to get a fix on what Domino can do, and that's why I ask. Apparently, there's already a "Spam" box on these Domino clients and a macro to add mail to the "Spam" box. Using your solution with fetchmail instead of kmail, I can automate training of SA via IMAP or POP. But, "Ham" is confusing. I'd suspect that a user would want to retain control of folder names, rather than lumping everything of value into a "Ham" folder. Am I correct in assuming that the user puts mail in the "Ham" folder only if it has been incorrectly marked as "Spam"? Then I suppose you're running auto-learn maybe, and the "Ham" folder corrects? Thanks for the hand-holding, this is all new stuff to me. -- Alan Gutierrez - [EMAIL PROTECTED] - http://engrm.com/blogometer/
