It's safe to assume that (almost) every e-mail address a mail is sent to, is receiving it. If they use webmail or exchange or pop3 or imap to read it, is everybodies guess. Only the mail server at cat.com and the addressee know. There's no feedback to the sender, unless he asks for a reading confirmation.
Hi everyone. This is my first post in the forum.
I am wondering how much information gets divulged between email accounts when doing POP mail forwarding.
For example, assume I have two email accounts , A@dog.com and B@cat.com, and that each is from a different email provider, "dog" and "cat." Account A is POP enabled and account B is configured to use POP to receive emails from account A.
Can the email provider for account A see which specific email account is using POP to access its mail? In other words can it see that B@cat.com is collecting the mail? Or can the email provider only see that email provider cat.com is collecting the mail?
