Delist Requests with XMission

XMission utilizes a combination of internal and external RBL (Real-time Blackhole List) lists to maintain the health of our email infrastructure and stop unwanted emails from hitting customer mail accounts.

In the XMission RBL Management system, IP addresses can be added to our blacklist or they can be whitelisted. A blacklist entry means the IP address(es) will be prevented from sending email to our system. Any sender on the blacklist will receive a bounceback message indicating they are blacklisted with details on how to be removed.

Check for IP Blacklist

Customers and senders can check if IP is on our blacklist here: https://postmaster.xmission.com/senders/rbls.php

The above URL is included the bounceback message response sent by the system.

Request Removal

If an IP is on our blacklist they can click the link above to request a delist or use this direct link: https://postmaster.xmission.com/senders/rbl_delist.php

Please note, an IP on our blacklist is not necessarily indicative of malicious activity by that particular user, IP addresses are somewhat ephemeral and can change hands frequently or may have been a previous source of abuse but subsequently cleaned up.

Once a delist request has been submitted it must be reviewed by a human to determine whether or not the IP address should be delisted. This process can take 1 to 2 business days.

If the request is legitimate, we will delist the IP address(es) provided and then send the template response back, letting the customer know that they have been delisted.

Requests that appear questionable will be denied and the IP address(es) will not be delisted. XMission will not send a response if we elect not to delist requested IP address(es).

Large Removal Requests

Removal requests for larger subnets, or a number of individual IP addresses, have to be submitted for administrative review and can take 1-4 business days to process.

IP Whitelist Requests

XMission email customers can submit IP whitelist requests to support@xmission.com.

Whitelisting an IP address or subnet can be useful for hosted email customers with remote end users, particularly those in foreign countries. This whitelisting can prevent automated system protections from blocking legitimate email on suspect networks. The whitelisting process requires human review and can take 1-3 business days to complete.
