Hi, Anyone else seeing issues with deliveries to outlook.com and subsequent mail.protection.outlook.com hosted domains? Looks like it started around 06:50 UTC.
On some deliveries after I send EHLO things goes silent and I timeout after 300s with loglines like this in my mta (Halon): Temporarily failed delivery to <some-outlook-hosted-address> (retry 0) in 300.107s: Network error: Read timeout (300s) waiting for data (EHLO) I noticed due to concurrency limits I've set up so my queue with unsent mails to outlook started to rise quite quickly when all slots were taken by hanging connections... A vast majority of the hanging connections are to 104.47.5.36 and 104.47.0.36 with deliveries to other IPs in their ranges going fine... -- BR/Mvh. Dan Malm, Systems Engineer, One.com
