I would like to propose a new Generic NDR Option: Custom Message: "Your email is being returned because you are an IDIOT!" . This would provide the Spammers with no information that they did not already know.  ------------- The Desperado Dan Seligmann. Work: http://www.mags.net Personal: http://www.desperado.com |

I see your point, it is a good idea. However, what would that serve considering that most emails are being sent from compromised home/business computers anyways on some bot network. So in that respect, the originating sender would usually never see the returned email. Thats also another reason I don't bother with NDR's because why send an email back to joe user when the message wasn't even sent from them in the first place but rather from a spammer that spoofed the address in the first place.

Thats why AuthorizedTo is so important, to eliminate those NDR's. For local mail servers its easy to use an API to pull a list and update SFE. For our remote (Exchange) customers we setup a SQL table and a form where they can enter their users & passwords and the script then injects this info directly into SFE. Customers maintain that list and we bill off of that list since we charge per mailbox. No NDR's and the extra traffic that goes with. Exchange customers understand their users won't ever receive any emails if they don't maintain their list. I imagine Postini does something similar as they don't have LDAP access to everybodys Exchange server. If it isn't in AuthorizedTo, it isn't getting past SFE ------------- http://www.webguyz.net |

mbrusl, Fro the most part, you are correct. The reason we, as an ISP do want the NDR in *mons* but not all cases is that there are many cases where the only way a valid sender knows what went wrong is our bounce. We service mostly businesses and truning off SDR's would cause a real tech support issue. WebGuys, HOWEVER .... I was simply venting my frustration above. ------------- The Desperado Dan Seligmann.
