Can anyone suggest a book or faq that will help me with setting startup parameters without the benefit of using eximon. I lease a dedicated server with Exim installed, but the vendor provides CPanel, which apparently blocks the use of eximon.

I want to try some tweeks for high mail volume, such as "split-spool" and changes to length of time underliverables stay in the queue.

Any suggestions? Thanks, Mike Ingram
