Perhaps it's like the documentation for UW-IMAP a few years ago. The documented config really seemed to be wrong, so based on trial and error testing and detailed documentation, I documented a config that worked well on several UW servers. Afterward, several people copied that config and replicated it to other sites recommending it as the ideal config for SM on UW-IMAP. > The default folder prefix value isn't something > that is going to be "non-optimal" when set some other way - it's not a > performance setting.

I can work with that. :) Thanks Paul. P.S. Saw Richard Underhill's quintet recently in a tiny club with me just two armlengths from Richard.
