Hi Pablo, you are quite right that IP is not listed in SCBL but it is listed in other places:


That includes lack of reverse DNS. Some people report SCBL even though they use other BL to reject your e-mail.

There are past reports of abuse here:

The server does not appear to be listed by Spamcop, so I'm guessing that the receiving ISP is simply using that as a generic error message.

A quick look on senderbase does show that it is listed on list.dsbl.org however.

Going to their page and reviewing the information provided indicates that your mail servers are possibly open relays, allowing anyone to send mail through them without any kind of validation.

To add to what the others have noted, I see that SpamCop states:

host = lutrol1492.impsat.net.ec (cached)

No recent reports, no history available

This would add credibility to the possibilty that SpamCop is being used as a generic label for all block lists.

Please "contact 480-505-8877" (Technical Support for GoDaddy Software in Scottsdale, Arizona, USA, Country Code 1) and speak to one of the GoDaddy Technical Support Representatives that can clear the block, email those same Representatives via support[at]supportwebsite.com, or find another way for your customer to contact their intended recipient. Thanks!
