@XfinityAlex Hello, I read that you have helped many with this issue, We have started to have delivery issues from our listserv server. Now on the server we getting throttled by comcast only with the following error 4.2.0 Throttled - https://postmaster.comcast.net/#RL000010 as well as https://postmaster.comcast.net/smtp-error-codes.php#RL000003. I have signed up for Validity and our email server has a SPF, DKIM, DMARC all set. The IP is 141.217.0.118. The domain name is lists.wayne.edu. I would appreciate any help you can provide. Thanks
