We are sorry you have reached this page because your domain has blocked for one of the following reasons:

- Your email server may be misconfigured.
- Your email server contains a virus and has been sending out spam.
- Someone in your organization may have a PC infected with a virus or botnet program.
- Your marketing department may be sending out bulk emails that do not comply with the CAN-SPAM Act.

nsZones is not attempting to block your emails and this domain is temporary listed.

The listing will expire automatically and free of charge 6 months after the last abuse from that domain. Expedited manual express delisting is available as an option, in case you do not want to wait for the automatic and free expiration.

For your domain delisting, you will be charged 5 Euro, using Paypal payment.

WARNING: Before requesting express delisting make sure the problem which caused the listing is fixed, otherwise you are at risk to get listed again if new abuse becomes known.
