Reduce the amount of junk e-mail you receive

The following are several ways that you can reduce the quantity of junk e-mail you receive.

Avoid replying to the sender with REMOVE in the subject line.

Messages you receive may include instructions (such as to reply with REMOVE in the subject line) on how to remove yourself from future mailings from the individual or organization. Unfortunately, many senders include these instructions in order to try to confirm that they've reached a working e-mail address, not to remove you from mailings. Unless you are unsubscribing from a mail distribution list that you signed up for, or you know the message sender, the best practice is to discard these messages without responding. Some messages contain a phone number to call, but many contain no information on how to stop future mailings. Often if you reply to these messages, you find that the return address or phone number is invalid or is that of someone other than the real sender.

Alter your e-mail address when posting.

Organizations that sell e-mail addresses use computer programs that scan Web pages and newsgroups to harvest e-mail addresses. If you display an e-mail address on a Web page or when posting to newsgroups, alter your e-mail address in such a way as to trick search programs but not confuse users. For example, if your e-mail address is pat@nwtraders.com, change it to patNOJUNKMAIL@nwtraders.com. Most users will know to remove NOJUNKMAIL from the address before using it, but search programs will not. 

Set up FILTERS on our email server.

If you have already made the mistake of replying to some junk mail and now it just won't stop....all is not lost.

You may create filters to "screen" out known "spam", but you need to consider a few things before you start to create filters. Many junk mailers don't use the same email address twice, so filtering by sender may not work. You can also create filters by content, so if you are constantly getting offers for "cheap trips", you can create a filter to automatically delete all email with the words "cheap trip" in the subject. 
Remember that the email filter has no way of knowing what you want to block or pass  For example, if want to block hotdeals@yahoo.com, be very specific. If you created a rule that blocked messages with yahoo.com in the "from" field, you would not receive any mail from anyone with yahoo.com in their address. By the same token, you might really want to block ALL messages from any address that has "hotdeals.com" in it.
