Aloha Andy, Thank you for your interest. On Feb 09, 2000, you Andy sent a message that said: ! What do you have for a processor? CPU: Pentium II/Xeon/Celeron (350.80-MHz 686-class CPU) ! What's the rough average size of user mailboxes? Lots of ! leave-mail-on-server types? The average is roughly 500K. But, the big mailboxes like to check their mail every 2 minutes. Make 'em feel important....hehe. I'm starting think that it 3.4's way of handling /var/mail. I had this same mail spool on a 2.1.7 box and it handled just fine. I'm thinking about splitting up /var/mail into sub-directories. Any thoughts? ! Andy ! ! ! At 09:17 AM 2/9/00 -1000, you wrote: ! >Aloha, ! > ! > I'm stumped!
