Can send but not receive from some domains
Posted on 2007-10-04
Here's the deal I installed a second email server in the company, moved all the mailboxes, added an MX record for the new server & added a reverse lookup zone. It all seemed well, emails were coming and going. Then we notice certain domains were not getting thru. Charter.net, Yahoo.com I can send to these but not receive. The charter account will receive from me, but when I send from charter nothing the email is never received. It does not show up in message tracking. And the charter account never receives a NDR. We receive email from most of our outside customers.
