That's your server generating an NDR as a result of the 5.1.1 message, so Mark's server never sent an NDR. I've just telnetted to Mark's server and manually sent a message to the same address - no NDR received. So, you cannot stop the other server from getting a message like that. The important thing for you is that you are not sending any NDR. Neil -----Original Message----- From: Cory D. [mailto:coryd@xxxxxxxxx] Sent: 14 August 2003 15:51 To: [ExchangeList] http://www.MSExchange.org/ I did a test Mark and this is what I got back: Your message did not reach some or all of the intended recipients. Subject: test Sent: 8/14/2003 9:47 AM The following recipient(s) could not be reached: abc@xxxxxxxxxxxxxxxxxxx on 8/14/2003 9:47 AM The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address. <mailxserver.euler.com #5.1.1 smtp;550 5.1.1 User unknown> I do not want them to even get this. I am trying to keep the traffic down we have been have problems with people hitting us with 1 msg/sec lating 2-10 min that is to many response back to the orginator. I am just looking at a way to cut the traffic back to them.

I'd have to test to be sure. And typically, I rebuilt my test E2k3 server the other day as a 5.5 server for some testing. :-( I'll report back when I get a chance to test again, unless anyone here has got an E2k3 server handy[1].

[mailto:coryd@xxxxxxxxx] Sent: 14 August 2003 14:42 To: [ExchangeList] http://www.MSExchange.org/ But does it add to traffic back to the originator if the user is not found. I do not want to acknowledge back to them if it does. Basically what I am looking for is a way not to respond if that person(s) are not in the GAL.

E2k3 has a new check box called 'Filter recipients who are not in the directory'. This means that, at the SMTP verb level, your server generates a '5.1.1 User Unknown' response to a message to a recipient not in your GAL. Also, no NDR is generated. Neil -----Original Message----- From: Cory D. [mailto:coryd@xxxxxxxxx] Sent: 13 August 2003 15:31 To: [ExchangeList] http://www.MSExchange.org/ That is a nice B-Log. But how can I disable NDR's, I am getting hit with people sending between 1 and 40 spam's/min/connection(as much as 4000) and I do not want the extra traffic of a NDR. I have already unchecked "allow delivery receipt message" and "allow non-delivery message". What I want is to be rude and just totally cut it off, like hanging up on a telemarketer. No response just an empty line. There has to be some sort of re-direct or reg hack. -----Original Message----- From: Ezzeldin, Ezzeldin S.

I have serious amounts of junkmail in the BadMail folder at one of my customers. The customer is Running Exchange 2000 SP3 and the Relay protaction is fine as far as I can see! The problem is that that the badmail foler rapidly builds up with junkmail addressed bogusmail@xxxxxxxxxxxx, nouser@xxxxxxxxxxxx, (where mydomain is the correct maildomain, but it can be anything before "mydomain.com") The problem is that the server acceppts mail for users/mailboxes that don't exist during the session and then wants to send an NDR. This however results in loads of NDR's in the BadMail folder. Is there any way of forcing Exchange to reject mail during the session for users/mailboxes that dont exist on the system? Many thanks in advance! ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: coryd@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: ezzeldin@xxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: coryd@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: neil.hobson@xxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ______________________________________________________ This email and any files transmitted with it are confidential and intended solely for the use of the individual to whom it is addressed.
