asked on

you do not have permission to send to this recipient.

I have an Exchange 2003 server
I am getting this error when I try and send to certain external domains via an e-mail list.

"you do not have permission to send to this recipient. For assistance, contact your system administrator"
mail1.domain.com #5.7.1 smtp;550 5.7.1 <User@Domain.com>... Relaying denied>

I had the user delete and readd the ones that she was having problems with but this did not resolve the issue.
I am however able to send to them when they are not in a list. I am not sure if recreating the whole list will resolve this.
It would also take quite sometime to recreate the list.

Please help

Is this problem with any external domain or to some perticular external domain?

To external Domains but just when they are sent using a list and blind Carbon Copy. I didnt know about the blind carbon copy until just a few minutes ago.

This is happening to more then just one domain, but not AOL or Earthlink. I have added Reverse DNS

When I telnet to the mailserver I get connected.
