I work at a bank. One of our correspondent bank's have been receiving error's on two of our users when they try to send our user's email. I also receive the email going to them with no problem. Asterisks replacing the name of our employee and place of employment for privacy reasons. The other bank is receiving an error back and I need to know if its us or them that has a problem.
Thanks in advance for your help.

I would imagine that your mail server has implemented SPF checking and your partner bank has no SPF record configured in their DNS.
See http://www.openspf.org/ for info on what SPF is and how to impliment.
Are you personally involved in the IT? Your profile says your 13-14 so a little hard to tell!

Gosh, I kinda wish I was 14. Long way from it. I am personally involved in IT, but we also have an offsite Network Admin. We have had very little problems with the mail server, so this is kind of new to me.
Is this the actual email or NDR they get back
Or does the body of the actual NDR email say something quite different than above?
5.0.0. is usually un unrecognized address
Possible the sender has Cached Exchange mode or Name Autocomplete on, and the recipients address has changed.
Possible the address hasnt been updated on their end
So when they send an email, its returned
You could have them try turning off Cached Exchange Mode
Also have them try to open a new email
Start to type the recipient address
when it comes up as an autocomplete option, delete it
The go back, create a new email, manually type in the corect address and send
There is also another possibility here
Have a look at the type of emails that get this NDR
Are they actaul emails, or are these meeting invites only..
If they are meeting invites, its posible the recipient has a delegate, or ghost delegate, that no longer has a valid email address
resulting in the sender getting an NDR
