What do I do if my email is rejected due to RBL?
If your email has rejected due to an RBL (Real-time Blackhole List), then please follow the steps below so you can send the email:
- The IP address will be in the error.
- Once you have found the IP address, scan any machines/devices related to that IP address and remove any malware/spyware/viruses.
- Go to https://lookup.abusix.com/ to see which RBLs the IP address is on and request de-listing from the appropriate section.
- After de-listing the IP address, you will be able to send the email again.
