I, too, have a 3-5 hour delay, but I thought it was something to do with my end and greylisting. Now I'm not sure . . . :/ Thanks, Kevin ^ permalink raw reply [nested|flat] 11+ messages in thread

Same applies to you as Kevin .. please send me the full headers of one that takes 'many hours' to deliver, and I'll check the logs for that specific one to see if I can determine the cause ... - ---- Marc G.

This sounds scaringly close to the problem we had on wwwmaster with it not delivering emails. Resolving separately looked fine, but sendmail couldn't resolve. Could it be symptoms of the same problem? //Magnus ^ permalink raw reply [nested|flat] 11+ messages in thread

For instance, if it got a failed response, would it cache that and re-use that later, pending it timing out in its own cache?

No, but your local resolver, which probably caches, almost certainly does.
