Error: blacklisted by BackScatterer.org
The idea of the method used is to regard an e-mail server as a source of spam if it returns an error message to somewhere other than the original message source. For example:
- client X sends a message to Y using server A
- server A then sends the message to server B which hosts Y's mail system
- server B is forced to bounce it because the recipient does not exist (or they have reached their quota or have an auto-responder set, etc.)
- it therefore bounces the message back to client X, whose mail system is hosted by server C
- server C receives an error message (or bounce) for a message that it did not send and therefore considers that server C is a source of spam
- Bluewin (www.bluewin.ch) supplies your Internet connection via an ADSL router
- Bluewin also provides the e-mail address John.Smith@bluewin.ch
- Infomaniak hosts the domain "domain.xyz"
- Infomaniak provides the e-mail address John.Smith@domain.xyz
- use the server mail.domain.xyz (Infomaniak) to send an e-mail from John.Smith@bluewin.ch (Bluewin)
- or, use the server smtp.bluewin.ch (Bluewin) to send an e-mail from John.Smith@domain.xyz (Infomaniak)
This situation, while absolutely standard and commonplace, is deemed to be a sign of spam by BackScatterer.org and will cause (for those using it) some e-mails to be rejected.
All you can do is potentially contact those people still using BackScatterer.org to explain to them that this system is no longer in keeping with current practice.
