Ah, yes. I was having a discussion with BSD folks about how I was missing the equivalent of "service reload sendmail", and they replied that I have no business managing my own mail server if I don't know I should send SIGHUP to the process. I said that's great but this is my home box and I don't see how it helps me to be an expert in every service that's running there. For large installations, sure, there should be a dedicated email person. But are smaller installations not allowed to run sendmail so that cron can send its messages to some central place?
