hotmail issues

We're having a lot of deferrals with connection timeouts for mail destined to hotmail.com, some of the IP's in question are accessable breifly from other locations before they start timing out as well. This is resulting in a lot of hotmail.com bound email backfilling in our queues. Is this some new tarpitting or throttling mechanism, anyone else experiencing it? Can a hotmail admin contact me off-list? -mark -- Mark Jeftovic <markjr@easydns.com> Co-founder, easyDNS Technologies Inc. ph. +1-(416)-535-8672 ext 225 fx. +1-(416)-535-0237
