iCloud addresses blocking my work domain emails I have a domain-based email for my Design Studio. Starting about a week or so ago, all emails sent to @icloud addresses have been blocked. All with a 554 error code such as. <address@icloud.com>: host mx02.mail.icloud.com[17.57.155.34] said: 554 5.7.0 Blocked - see https://support.proofpoint.com/dnsbl-lookup.cgi?ip=[redacted] (in reply to RCPT TO command) Four inquires to proofPoint have produced no response or relief. Is there any way to clean this up Apparently iCloud has decided I'm "bad" or something.... This also happens attempting to send to my own iCloud address! Frustrating!

ATT (currently.com, sbcglobal.net) is blocking emails sent from icloud.com account Mail Delivery System says this--- This is a system-generated message to inform you that your email could not be delivered to one or more recipients. Details of the email and the error are as follows: Various IP addresses and hosts are identified, and it says that that the iCloud.com account is blocked. But no action was taken on either of two ATT accounts to block any email address or IP number.
