I fixed my server this morning. It stopped sending and delivering email sometime around Tuesday. It was wierd because when I would tell QMail to process the queue, it would act as if it was doing so, and it would do nothing… I found out that the network segment that it was on was replaced right around the time it started to hiccup. The server was not powered down at all, so perhaps something in the TCP/IP stack got messed up. Anyway, it is working now…
