Email & SMTP authentication

[Phil Tomlinson]

Dear SMUGGERS

Can anyone explain this annoying email problem to me?

I have been trying to send emails to a company. These emails get returned to me saying  

“550-Please turn on SMTP Authentication in your mail client.

   550-st43p00im-zteg10073501.me.com [17.58.63.180]:33051 is not permitted to

   550 relay through this server without authentication. (in reply to RCPT TO

   command)”

All my other emails get sent successfully. I use Apple Mail and the iCloud server.

Looks like a misconfiguration on the recipient’s server to me, especially if all other mails send correctly.
