Keep getting same spam and then Undeliverable message to some other user for that same email
I keep getting the same email over and over-- twice a day. The email also has the sender as being from myself to myself.
The user name changes but everything else is the same. The tile of the email is November 75% Off

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.

I know I didnt send this email, and it isnt in my sent folder. I went to MXtoolbox.com to verify if my server is an open relay and it said i wasnt. I did go to one other site (cant recall) that mentioned it was an open relay. We had an open relay two years ago but we ended up fixing it and got off all the blacklists.
Any help with this annoying problem would be appreciated.

Okay..I know how to disable NDR but would this have an effect on anything else?
Emails coming in to our server can have an invalid user name but will not get kicked back to the original sender. All of those emails get sent to our catchall box. So in a sense we arent sending out NDR's..right?

It's a bad idea to disable NDR's on your server all together. You will likely get blacklisted.
Correct, your server should not be sending NDR's if a bogus@yourcompany.com email comes in if you have a catchall box.
What kinda of antivirus/antispam program do you use? Many of these have a 'directory harvesting' feature like a catchall box that will just delete the email and not send out a NDR.

We are using GFI Mail Essentials for our Spam blocker.
OK, that's what i use too.
In your mailessentials configuration --> anti-spam --> Directory Harvesting --> properties. On the 'general' tab, it should be enabled. Then on the 'other' tab you should have 'generate Non Delivery Repots (NDR) unchecked.
You should be all set to go.

I checked and everything was configured as you instructed.
My last question.
Company A is getting email with a spoofed address pointing back to my company. Couldnt that companyt possibly get us blacklisted even though the email never came from us? I would assume that the senders name isnt looked at for blacklists but the IP address is?

Yes, I think you are exactly right. The company sending fake emails are most certain on blacklists, that is if they aren't spoofing their IP as well.
