Hello List, we experience problems sending mails to Microsoft/Office365 for a few days.
We get the following error: Nov 25 09:04:00 athena postfix/smtp[8143]: 9528122403CF: to=<[email protected]>, relay=dreamcatchergmbh-de.mail.protection.outlook.com[213.199.154.106]:25, delay=6.2, delays=0.57/0.02/0.39/5.3, dsn=5.7.511, status=bounced (host dreamcatchergmbh-de.mail.protection.outlook.com[213.199.154.106] said: 550 5.7.511 Access denied, banned sender[176.9.44.186].

AS(508) (in reply to RCPT TO command)) Is anybody else experiencing this problem? I've done the following: - sent mail to delist@ messaging.microsoft.com - https://sender.office.com/ - https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&locale=en-us&ccsid=635806049111602712 Result: None. The forms gave me the info, that the IP is not blocked. The mail responded with text blocks. There is no blocking in the Exchange admin center. I would appreciate any help from the list. Thanks in advance.
