I have a friend.  We'll call him Layton (because that is his name).  For years, he has been able to send me emails.  Then a few days ago, the system broke.  He cannot get an email to my .mac account.  Here is what I know:


1.  He can send emails to my work email account.

2.  No one else has a problem getting emails to my .mac account.

3.  His emails are not going into the junk folder.

4.  I can send emails to him.

5.  Here is the message that he is getting when he tries to send me emails:


[I have replaced my name and Layton's name with "abcde"]

What can we do to get communications flowing again?

    ProofPoint is filtering for iCloud and suddenly very aggressively.  Many false positives.  I have the same problem sending from my domain to mac/me adddresses.  I have reported the problem to proofpoint but no resolution yet.  Somehow need to escalate this to Apple''s attention because it is a problem for them if their customers cannot receive legitimate email.

    I, too, am now on Proofpoint's blocked list and unable to unblock my e-mail forwarding from earthlink to Apple. Since all of my e-mail correspondents now think my address is bogus, I am unreachable. Whoever hired Proofpoint needs to fix this problem.

    You will need to report the false positive blocking to iCloud support. Be patient, some of the technicians are a little fuzzy on the concept. I think Apple needs to fire Proofpoint since they are taking money to make their users pretty unhappy. My e-mail forwarding from my business address to my iCloud address was falsely blocked and all of my correspondents got messages which made them think that my address no longer worked.

    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
