apple-idemail
A while back I had added a secondary email address to Apple ID which had not belonged to me. A few years later I keep receiving messages of activity of that account (reset the password, change of details, etc.).
My Apple ID account is not associated with that account, I just receive emails from that account with information, because I added my mail as secondary mail.
I do not want to receive these emails. I cannot reach this person.
Mail.app has a feature called rules that enables you to automate your mail tasks.
You can define rules in the Mail preferences.
First, just clearing my doubt, did he try checking the mail in a popular browser or any device? , just a guess, may be due to the browser agent, he might not be able to view the image or link.
Now if this is not working he has another option to use the secret question option. If he doesn't remember that , just ask him to mail apple support with his mail id and username ,and they can help you , they really do too..

I do know this person but did not want to contact. Apple Support could not intervene either as it is prohibited for them to change user's data.
Albeit, I have contacted that person and we have solved that issue.
