RE: [IMail Forum] Help with listing on ORDB.org !!!

If I am your customer that you host mail for and I do important business with a large EDU that relies on RFC.  All of a sudden, I can’t send mail to them because you refuse NULL senders.  Rejected every time.  What do you do?   Wes From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Kiiskila Sent: Wednesday, April 21, 2004 2:35 PM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Help with listing on ORDB.org !!!   Ditto here. The RFC’s were probably written when no one even considered the impact of spam.   IMHO Null sender should only be allowed from automated processes (scripts in your servers to tell you when processes fail etc) within your own network address range, there ought to be an option (or update to the RFC even) to allow refuse null sender from outside your ip range and still be compliant.   Don Kiiskila Network Administrator Snapstream Media LLC http://www.snapstream.com "You cannot make anything fool-proof.

They report: ----------------------------------------------------------------------------------- Return-Path: <[EMAIL PROTECTED]> X-Original-To: [EMAIL PROTECTED] Delivered-To: [EMAIL PROTECTED] Received: from mail.cydian.com (emailconfig.cydian.com [208.34.50.132])         by bockscar.ordb.org (Postfix) with ESMTP id F2189557C         for <[EMAIL PROTECTED]>; Tue, 20 Apr 2004 13:24:53 +0000 (GMT) Received: from localhost.localdomain [212.242.88.2] by mail.cydian.com with ESMTP   (SMTPD32-7.07) id A49B8C009C; Tue, 20 Apr 2004 09:24:43 -0400 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] X-ORDB-Envelope-From: [EMAIL PROTECTED] X-ORDB-Envelope-To: [EMAIL PROTECTED] Subject: ORDB.org check (0.7097115109686880.8643653302) ip=208.34.50.132 Message-Id: <[EMAIL PROTECTED]> Date: Tue, 20 Apr 2004 13:24:53 +0000 (GMT) ----------------------------------------------------------------------------------- Obviously, they're sending as "[EMAIL PROTECTED]" My question is how? This account not only has a long cryptic password, but is disabled. I know I can't delete the account. On the admin screen, I've checked: User Cannot Change Password, Account is Disabled, and Hide from Information Services. Not checked: User cannot modify LDAP attributes, allow web access, host administrator, list administrator, imail system administrator On SMTP security, I have slected: --------------------------------- * relay for local users only and checked: --------------------------------- allow remote mail to local groups refuse null() senders check valid sender auto-deny possible hack attempts disable SMTP-VRFY command and not checked: --------------------------------- allow remote view of local groups disable SMTP-AUTH reporting Am I missing anything? Does anyone have any ideas on this?  I'm getting irate calls from customers whose email are getting bounced, and from what I can see, it should be config'd correctly. Thanks! Chris
