How to prevent your server / hosting IP being blacklisted by spammers!
Your default inbox is probably full of spam without your knowledge!
When a spammer sends a blind email (firstname.lastname@example.org) to your domain the server sends a bounce notification to the reply to address in the spam email. That’s a major problem! Here’s how to fix it.
A client recently was getting bounce messages from AOL who blacklisted the sending IP address. To make a long story somewhat short. A spammer had used a forged mail from and reply to address of an AOL member. Then that member complained to AOL who blocked the mail servers IP.
If your using cPanel this is an easy fix. Login to your cPanel and select default address under the mail section. Click any thumbnail for a larger image opens in a fancybox.
This is the best way to handle unrouted email that’s sent to your domain.
Click the Default Address icon. Set any “unrouted” email to go into a blackhole. This prevents sending bounce notifications to the person that had their email address hijacked by spammers.
This will not effect normal routed email set up in your hosting account.
