You’re listed on SBL

What does SpamHaus says about IP being listed on SBL

IP addresses are listed on the SBL because they appear to Spamhaus to be under the control of, used by, or made available for use by spammers and abusers in unsolicited bulk email or other types of Internet-based abuse that threatens networks or users.

The Spamhaus definition of “spam” is “unsolicited bulk email” (UBE). Spamhaus does not evaluate the content or legality of the contents of an email message, merely whether that message constitutes spam by this definition.

It is very important that you get your IP removed from SBL by visiting this url.

What does SpamHaus says about IP being listed on XBL

In order to maintain the utility of the XBL and to prevent bad actors from using the information to evade XBL listings, Spamhaus does not reveal the precise behaviors that typically result in an XBL listing. Generally speaking, however, those behaviors can include:

• The presence of malware inadvertently downloaded on a device.
• Security problems on devices allowing unauthorized access and malicious activities unknown to its legitimate user.
• “Free VPN” type applications using the customer device as a proxy to do network activity on behalf of other unknown people.
• Participation in brute force attacks on a specified service.
• Rapid changes in identity while attempting to deliver mail.
• Frequent sinkhole connections in a manner consistent with malware activity.
• Attempts to relay mail using illegitimately obtained credentials.

XBL listings will automatically expire after a period of time once the malicious behavior is no longer detected.
