Anyone else seeing this? I've tested from a few off-net points and am seeing the same. Mail is starting to pile up in our queues in quantity. Given the scale of what this appears to be I assume the team is already hard at work on it, but the lack of mention here concerns me, so sorry for the noise if this is too obvious for the list ;-). Our primary outbound relays are within 64.253.128.0/19 Here are a couple representative logs: 2016-05-25T12:55:19.470647-07:00 skaro postfix/smtp[6486]: connect to mx1.hotmail.com[65.55.37.104]:25: Connection timed out 2016-05-25T12:55:49.504155-07:00 skaro postfix/smtp[6486]: connect to mx1.hotmail.com[207.46.8.167]:25: Connection timed out 2016-05-25T12:55:49.513775-07:00 skaro postfix/smtp[6486]: connect to mx2.hotmail.com[65.55.33.119]:25: Connection refused 2016-05-25T12:56:19.550093-07:00 skaro postfix/smtp[6486]: connect to mx1.hotmail.com[134.170.2.199]:25: Connection timed out 2016-05-25T12:56:49.583216-07:00 skaro postfix/smtp[6486]: connect to mx1.hotmail.com[65.54.188.110]:25: Connection timed out 2016-05-25T12:56:49.585566-07:00 skaro postfix/smtp[6486]: 3F2D5FFC9B: to=<indra_...@hotmail.com>, relay=none, delay=120, delays=0.17/0/120/0, dsn=4.4.1, status=deferred (connect to mx1.hotmail.com[65.54.188.110]:25: Connection timed out) 2016-05-25T12:59:32.971606-07:00 skaro postfix/smtp[5033]: connect to mx3.hotmail.com[65.55.37.72]:25: Connection timed out 2016-05-25T12:59:32.995152-07:00 skaro postfix/smtp[5033]: connect to mx4.hotmail.com[65.54.188.126]:25: Connection refused 2016-05-25T13:00:03.033047-07:00 skaro postfix/smtp[5033]: connect to mx2.hotmail.com[207.46.8.167]:25: Connection timed out 2016-05-25T13:00:33.066589-07:00 skaro postfix/smtp[5033]: connect to mx4.hotmail.com[207.46.8.199]:25: Connection timed out 2016-05-25T13:00:33.076153-07:00 skaro postfix/smtp[5033]: connect to mx2.hotmail.com[65.55.33.119]:25: Connection refused 2016-05-25T13:00:33.080762-07:00 skaro postfix/smtp[5033]: 25B4FFFC00: to=<cynthia_lamber...@outlook.com>, relay=none, delay=91, delays=0.78/0/90/0, dsn=4.4.1, status=deferred (connect to mx2.hotmail.com[65.55.33.119]:25: Connection refused) 2016-05-25T13:02:08.167728-07:00 skaro postfix/smtp[7967]: connect to mx4.hotmail.com[65.55.37.88]:25: Connection timed out 2016-05-25T13:02:08.177325-07:00 skaro postfix/smtp[7967]: connect to mx4.hotmail.com[65.55.37.120]:25: Connection refused 2016-05-25T13:02:38.208945-07:00 skaro postfix/smtp[7967]: connect to mx1.hotmail.com[65.54.188.72]:25: Connection timed out 2016-05-25T13:03:08.242467-07:00 skaro postfix/smtp[7967]: connect to mx1.hotmail.com[207.46.8.167]:25: Connection timed out 2016-05-25T13:03:38.275974-07:00 skaro postfix/smtp[7967]: connect to mx3.hotmail.com[207.46.8.199]:25: Connection timed out 2016-05-25T13:03:38.278894-07:00 skaro postfix/smtp[7967]: 7DA71FFC4D: to=<brendayle...@outlook.com>, relay=none, delay=3265, delays=3145/0/120/0, dsn=4.4.1, status=deferred (connect to mx3.hotmail.com[207.46.8.199]:25: Connection timed out) Keenan Stargate Connections AS19171 _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
