don't perform backscatter tests on ISPIP messages
by Patrick Neill

Rate this Message:
Some of my users are forwarding messages from their ISP e-mail account onto an e-mail account behind ASSP.
Problem: ASSP obviously doesn't have a MSGID for these messages and marks them as backscatter. Could an option excluding messages from an ISPIP from backscatter test solve the problem ? |

So there's the problem... make the forwarder rewrite the envelope sender properly... -- Best regards, Charles ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

They are the largest ISP in this country. Why should they want to do anything for their customers ?

>Could an option excluding messages from an ISPIP from backscatter test solve the problem ? This option could not be a switch "DoNotBackScatteronISPIP". If anyone gets all his emails from ISPIP's, he would not have a choice! So, I think an option "noBackScatterIP", which could be a file with IP's, could solve this problem?! But you'll have to register your ISPIP's in two options separately! Thomas

If from the remote server, a null sender seems like a very poorly configured system. You might drop a line to their admin. Otherwise, is there no commonality to the messages which you could use for red- and/or white-listing? -- Daniel ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

There is a new option added to config : noBackSctrIP - any defined IP will not be check for backscattering! 'ispHostnames' is used for DNS-Backscatter-check instead of the real IP - if it is found! Thomas

The speed with which changes are implemented in ASSP is amazing !
The IP based exclusion is working nicely. Thank you very much.
