Controlling receipt of emails to one user account only

There are three user accounts on my PC. Emails are recieved by whoever is on their account at the time. How can I restrict the reciept of emails to one user account only thus stopping my son from recieving my emails if he happens to be in his area (user account) at the time.

 

That's an e-mail thingy not an operating system thing.
Usually people set up different screen names in the Internet account requiring different passwords to access them.

Don't know of ANY Internet account (AOL, EarthLink, Comcast) that doesn't provide various scrn names n passwords.

 

You can set up rules to direct new messages to various folders based on a number of criteria including who it is addressed to.

The inbound mail will never stop in the general 'inbox' but you would set up new folders like 'Dads Inbox', 'Brats Inbox', etc. and the posts would do directly to those folders. He couldn't see yours and you couldn't see his unless you are on with an admin account and did some looking around. At least I hope you don't have him set up as an admin on the PC.

For specifics, you need to say what email client you are using since they behave a little differently for this feature.
