Hello Jonnyb941,


Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with sending email to a particular client. The related article at the top of the page is a great place to start.


"When refusing SMTP transactions, our mail servers generate SMTP errors with information about why your connection or message was rejected. To find the error message, check your mail logs. Most of the errors will also include a URL that provides more information."


Please also refer to the section titled "Contact us" for further support.


We hope this helps.


Cheers!
