smtp - Preventing Recipients from getting an email. - How Email Processing Works? -


when send email this:

from: jeff@yahoo.com to: xxx@aol.com, xxx@aol.com, xxx@aol.com cc: james@gmail.com

which mail server sends message via email recipients in & cc field? smtp server or server owned recipient (like aol.com)?

when write email , send it, hand off smtp server have access to. server contact recipients server (or intermediate server) , deliver email smtp server. smtp server on receiving end somehow, depending on setup, deliver email users.

in example, give yahoo.com's smtp server email. server contact aol.com , deliver email there. contact gmail.com , deliver email smtp server.

you should read part of smtp rfc have explanation process.

how go preventing email delivered, somehow control 1 of smtp servers contacted in process - or not send email @ all. when see email delivered in own mailbox, way late trying prevent other recipients receiving email.
