NetEase maintains gateway level blocks for networks that are known offenders
of our network policies. In most cases this is considered as a last resort method when attempts to stop abuse have failed.
If you are a network administrator and you feel that your network has been blocked wrongly, you may contact our office
via telephone at 731-845-5640 and ask to speak to the Abuse desk. You may also use the form provided or you will have to obtain e-mail
services through a trusted site and e-mail abuse@netease.net with your information.
Although our ultimate goal is to provide a free flow of information through our network, we will not tolerate network abuse in any form.
NetEase actively monitors attempted network abuse and maintains effective means of
filtering un-solicited mail as well as attempts to relay (bounce) mail through the NetEase network. NetEase
has been successful in prosecuting network abuse offenders and our Network Abuse Staff works closely with
several Internet providers in matters related to network abuse.
NetEase Mail Servers are protected against un-wanted UCE/UBE utilizing blocking list maintained by
various blocking systems available on the Internet. If your e-mail is blocked by one of these blocking list then your server has been identified as a spam source or open relay.
Our suggestion is to fix the problem. If you are unable to fix your server, then perhaps you should consider not running such an MTA connected on the Internet.
If you feel your server has been rejected unjustly fill out the following form. We will research our abuse reports and mail logs and determine whether your server OR e-mail is eligible for our whitelist.
