Anyone who uses our mail services should add our mail servers to your whitelist or trusted servers list. See the resource access page for a current list of IP addresses. If you are publishing an SPF record for your domain, we recommend adding “include:spf.rollernet.us” to your SPF record. Failure to whitelist our servers from additional filtering may violate our backscatter prevention policy.
