This problem crops up from time to time with our customers so if you receive an error like this when you try to send your email:

‘Your outgoing (SMTP) e-mail server has reported an internal error.

If you continue to receive this message, contact your server
administrator or Internet service provider (ISP).

The server responded: rblsmtpd: 0.0.0.0.0 pid 7423: 451
http://www.spamhaus.org/query/bl?ip=0.0.0.0.0′

This means your ISP (Broadband provider’s) IP address is listed with one of the main spam database’s which most mail servers use. (In this case Spamhaus).

If they are listed you will have problems sending email and automatically receive this message so the best thing to do is go to your domain’s Webmail address and send from there instead, the address is as follows:

webmail.yourdomain.com

(obviously replace yourdomain.com with your domain name).

Username = the first part of your email address, eg. sales

Password = the corresponding email password.

Your ISP should be aware of the block and will be taking steps to remove their IP from the list.
