If you are receiving a large number of replies or bouncebacks for emails that you didn’t send, or from email addresses that show your domain but don’t exist, you may have been spammed.
There’s a spoofing technique where a spammer sends huge volumes of email messages that appear to be from you or someone other than the actual source. Spammers often use a random address in their spam list as the From address to disguise the true source.
Here are some ways you can protect yourself and your email account from being spammed:
- Don’t unsubscribe from a spam email. That lets spammers know they have a valid email address.
- Create a separate email address strictly for use on websites.
- If you have the catch-all feature for your domain turned on, temporarily turn it off.
- Set up an SPF record to prevent further abuse to your domain.
