Comcast Block Removal
If you are a Comcast customer having difficulty sending to another domain, this
unblock will not help. Instead please contact
Comcast Customer Security Assurance.
This form will only assist in unblocking if the error you received contains the
error code BL000000. For all other blocks, please follow the link contained within
the error for more information.
By making use of our RBL Removal Form,
Comcast will evaluate your request. Typically it will take less than 30 minutes
for the block to be lifted. However there are some instances where we will
report that the block cannot be lifted without first contacting
Comcast Customer Security Assurance.
Please note that Comcast does limit the number of requests that can be made through the online form. We will not accept the same IP to be requested more than 5 times per day or for a requester to enter more than 20 IPs per day.
