First of all, Chris's instructions worked for me the first time, even though I had little idea the theory behind any of it (newbie to unix). However, per Ben's (benwillies) comment, there was a significant delay. So, I followed his instructions to speed it up. Yep, it was fast, but it stopped sending e-mail--no errors either, other than in the log it did not have the phrase "relay=excellent..." like it did right after I did Chris's initial changes. I'm sending e-mail to an outside address, like firstname.lastname@example.org (I have no idea what Cron is ). Any, this was my experience.
