I adjusted the monitoring to look at when mailman delivered the first message to exim for an external delivery. I noticed delayed messages pretty quickly, the longest being 40 minutes this evening. So, now I'm working on eliminating the delays. I'll post most details of how that is going in the next few days. My first idea is to try making exim receive faster from mailman by avoiding dns lookups during the smtp session with mailman.
