How to Deal with Spammers Forging Your Email Address

Have you had spammers send out email that looks like it is coming from you? You have probably gotten spam that identified your email name and/or email address as the sender. Here are some helpful tips from Modwest, a domain hosting site used by some of our clients.

Disable "catch-all" email addresses: If Modwest handles your email and you receive spam sent to an email address at your domain that is not listed in your Modwest Onsite control panel, then you may have setup a "catch-all" email address. Disabling it will stop you from "catching-all" the spam sent to these nonexistent email addresses.

Blacklist yourself: Yep, that's what we said. If you receive spam email that appears to come from your own email address, you can stop it by adding your email address to the "Known Spammers" list in your Modwest spam filter. NOTE: This is not a solution for those whose email needs include emailing themselves.

Beef up your spam filter: Email forged to come from your address without your permission will be spam, so make sure your spam filter is on and set to an effective level.

Kill the messenger (at least temporarily): If you are receiving tons of nondelivery and other bounce notifications because undeliverable messages appear to come FROM your address, you should temporarily put the sender of these bounce-back messages (such as 'postmaster@*' or 'mailer-daemon@*') on your "Known Spammers" list in your Junkmail or Modwest spam filter. NOTE: This will prevent legitimate emails from 'postmaster@*' and 'mailer-daemon@*' from going to your inbox.

Call the (spam)cops: Spamcop works with internet service providers to cut spam off at its source. You can report spam you receive at spamcop.net

Granted: You may not be able to do some of these steps exactly this way if you do not have a Modwest account, but these tips should give you an idea of how to deal with spammers on your terms. While you are at it, be sure to Whitelist JCIGroup.com.
