Rogue email address in the From list when composing an email
Hello,
This morning I was writing an email on my iPhone 7 plus and I hit the from field to change the email address account from my default and I noticed a rogue email address in the list that is not mine nor is it familiar. It is a long name with numbers @my.minibox.email. This doesn't belong to me and when I look in passwords and accounts this email address is not in there. I am quite concerned on how it got there and what it is doing to my email accounts/phone. Everything about email is functioning normally.
Has anyone experienced this or know what I need to do to get rid of it? Is it malware?
Thanks in advance!
iPhone 7 Plus, iOS 13
