I have a new iPhone 18 Pro running iOS 27.0.1 and I am having problem sending email to one person in my Contacts (so far) from the Mail app on the phone. Every time I send him an email, it is returned with this error:
552 5.2.0
Message contains bare CR and is violating 822.bis section 2.3 (in reply to
end of DATA command)
I would appreciate any help. Thanks.
