Howdy, Since about 6:50 AM EDT (GMT -04:00) all of our outbound mail hosts have been getting a mix between timeouts and the following back from mx.cogeco.ca (216.221.81.26): 421 #4.4.5 Too many connections to this listener. I tried from a few IPs in subnets that have no previous reputation (that I know of, anyway) and am getting the same thing. Is anyone else experiencing this?
