How does one block a contact on Gmail so the sender receives a note that their email has not been delivered?

The answers given above are for blocking mail addresses, but if you do it that way, the contact will not get a message that his mail was not delivered. The only program I know which is able to send a fake "address not found" message is Mailwasher.





Set up your email account(s) in MailWasher and hit the "Check Mail" button. It then downloads all new message headers and displays message details alongside each one (priority, subject, from, to, etc.). Any email that MailWasher considers to be spam is highlighted for easy sorting.





Two checkboxes are located next to each message header: "Delete" and "Bounce". If you click "Delete" the email will be marked for deletion, click "Bounce" and the mail will be marked for bouncing - a fake "address not found" email will be sent to the sender. Once you have decided what to bounce and delete, click "Process Mail" to get it done and your mail client launched for downloading all accepted emails.





MailWasher has a "blacklist" and a "friends list" to enter good and bad email addresses. Addresses in the blacklist are marked for deletion, and addresses in the friends list will be marked as okay. Filters can be set to increase MailWasher's effectiveness. You can have email addressed to "undisclosed recipients" automatically deleted and bounced for example.





Note: the program is free but limited to one email account. MW Pro supports multiple mail accounts.

Reply:This is instructions for Yahoo, but you should be able to find similar equivalents in Gmail.


Look for the 'Options' link at upper right corner of mail screen and click on it


Options /mail options / blocked addresses


Enter the E-mail address you wish blocked and click on 'add block'


you will never get mail from that address again.
Reply:Open your contacts list. Select the contact you want to block. On the right side there is a drop down menu beside "show in chat". From the drop down, choose block. I believe it blocks them from email as well as chat.
