Fixing Email Bounces
Rumkin.com uses some pretty strict spam filters to try to make email reading pleasurable for its users. If your email gets "bounced" back to you, and you are positive that you have the right email address, then we need to figure out why you were banned.
Step 1: Look at bounce message
You likely received something like this:
Step 2: Find the reason your message was bounced
This is the "mail denied, based on relay 188.8.131.52" part. This means that the email that you sent was blocked by the anti-spam filters because the mail host you use is known to send spam. That set of numbers at the end is vital. Write them down.
Step 3: Check out the mail relay
This may give you more information on why the server was denied and it will tell you what particular filter is giving you problems. Go to the RBL Check page and type in the set of numbers, including the decimal points. (For the above example, you will want to type in "184.108.40.206" without the quotes.)
When you get the results, you will see something like this:
According to those results, the only one that is not "Ok" is list.dsbl.org. Now you know which particular filter bounced your message.
Step 4: Tell me
The general anti-spam policy at Rumkin.com is to let all good messages in and as few spam messages in. If your messages are being blocked, you now need to let me know. You must use this Contact Form instead of regular email (because your email is being blocked). When you fill out the form, make sure to include the following information:
When I get to your email, I will unblock your host and possibly stop using that particular filter so that your future emails will get through properly.
