Exchange 2003 do not have permission to send to this recipient; rejected by user Open Relay? I checked

500 POINTS HERE, this is URGENT

I have recently set up an exchange server 2003, everything works great, except when we try to send to one particular email address, We immediately get the following bounceback.

The following recipient(s) could not be reached:

'USERNAME@umn.edu' on 10/14/2004 12:40 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mailserver.qualityforum.org #5.7.1 smtp;550 5.7.1 <USERNAME@umn.edu>... Rejected by user; see: <http://umn.edu/mc/p?EAxF35zhbdHzNdTyv6TG8CNknYgRdfMR9$HqK7FRoWdTjrp2rczX3KTPq5sJ5N6QanneyGAGADrv7o8dwwf1wgA>>

The recipient said they ran us through open relay databases, and we came up dirty. I ran it before I rolled it out, and thoroughly checked it, and found no evidence of an open relay. Today I did the same thing after reading the response from the recipient and they all came up clean.

PLEASE HELP, I need this fixed like it was yesterday.

Thanks ahead of time,
Devon

try dnsstuff.com it seems u are blcklisted.

Vahik

forgot to say u could ask the other end user or admin to put u on white list which will
override the blacklist.then create an smtp connector for that domain and send all ur email
straight to their public address.

Where in dnsstuff.com does it say I am blacklisted? Think only hint I have it says in the Spam SBBl has a DNS lookup issue. I was thinking the whitelist route, but If I have an open relay issue, I want that fire put out now before it starts. They are a royal PITA. I thought I had the server locked down, but I kind of think it's a UMN issue. Am I right? Or am I just not seeing how blacklisted I am becoming as I write this?

Thanks
Devon

I also want to add that when I go to dnsreport.com it says "[ERROR: The parent servers say that the domain mail.qualityforum.org does not have any NS records (although they may have some other information on that zone). I can not do a DNS report on a hostname (such as mail.example.com) or a domain name that does not have its own zone.]"

make any sense? when I ran it on DNSREPORTS Sunday, it worked fine.....puzzled....

They are NOT relay proof with a fresh install. That is just a ludicrous thing to say.

Didn't mean to give a grade B guys, I apologize. It was an A, because you enlightened me to a few things. The problem wound up being that we were blacklisted Januray 2004 for excessive outgoing virus'. This was unbeknownst to ANY of us in the organization because we never had any issues. Our virus tables were always up to date, and our Trend Scanmail had performed flawlessly <so I thought>. Nonetheless, I made a request to the "SysOp" at UMN.EDU and told him that information was false, and he added us to their "list".

I still don't understand why this just arose from the new installation. The dates were ANCIENT (6 months ago) . I guess it's one of those blackhole effect thingy's........dunno....I like to think logically, so this throws me.

Thanks for all of your help Vahik and nalanbar! I will use those techniques for other clients in the future.

Take care,
Devon
