Sent Email not received by recipient
I have had a number of instances where I have sent an email to a particular recipient and it has not arrived although they claim to be receiving mail from other people. This has happened using both MacOS and IOS mail.
As a check that I had not misspelt the address I tried replying to a mail from them.
Is there anyway that I can trace the journey of the email similar to what we can do for incoming mails.
Help please
