Hi, We're starting to see bounces on Hotmail.fr that we think are linked to the new mx on this domain:
hotmail.fr MX preference = 5, mail exchanger = mx2.hotmail.com hotmail.fr MX preference = 5, mail exchanger = mx3.hotmail.com hotmail.fr MX preference = 5, mail exchanger = mx4.hotmail.com hotmail.fr MX preference = 2, mail exchanger = hotmail-fr.olc.protection.outlook.com hotmail.fr MX preference = 5, mail exchanger = mx1.hotmail.com the bounces 421 4.4.2 Message submission rate for this client has exceeded the configured limit are all coming from the new MX (hotmail-fr.olc.protection.outlook.com (104.47.9.33)) When mails are retried on the "usual" mx (mx1.hotmail.com) they are delivered fine (or may bounce but for other reasons).
