My client has regular pop3 email boxes from Godaddy, which recently have been spoofed. Basically, someone is sending emails using their email addresses requesting payments or loans. I changed their passwords, scanned their machines, and am pretty sure these emails are not coming from my clients' PCs. After I spoke to Godaddy, they recommended I switch to Office 365 email boxes because of encryption.
What I am skeptical about is, if all they are using is the email addresses that they know exist, how does encryption of the email stop this type of spoofing? It feels as though someone just saw my name on the website, and decided to use that name to register for something.
Unless my name itself is encrypted, I cannot stop that person from impersonating me, so why does encrypted email stop spoofing?
