If your IP address is included in any of the blacklists (RBLs) on this page, you will not be able to send emails to Fasthosts customers.

Note: We use local copies of these RBLs so removals may not appear immediately.

What to do next...

If you are sending emails through your ISP's mailserver

Any internet service provider who does not actively take precautions to limit the likelihood of unsolicited email being sent through their servers, runs the risk of having the IP addresses involved blacklisted. If your ISP's mail server has been identified by a blacklist as a source of unwanted or abusive email you should contact them directly. They may require the header of a bounced email to investigate fully, as this will provide them with the originating IP address and the reason why the email was not delivered.

If you are the administrator of the blacklisted IP address

You have been listed as a complaint has been made regarding unsolicited or abusive email originating from this mail server. Additionally this server may be listed as an open proxy, relay, or may be an exploited machine. As the administrator of the IP address listed above you should ensure that no unsolicited email is sent from this IP address.These details can be found in the link provided within the returned email, or by clicking the "More details" link in the list shown above.

If you are sending emails directly from a dynamic IP address

Due to the increase in trojans and viruses sending spam from infected machines, almost all emails originating from dynamic IP addresses are regarded as spam. To protect our customers' interests, we are not able to accept email directly from a dynamic IP address. If you are using a dynamic IP address please ensure that you are sending email via a designated SMTP server. This server will either be provided by your ISP or by the provider of your email service.
