I cannot send to one specific addresses. I have verified that the address is good as I can send from other email accounts not on this server and they go right through and also we could send to this client address from our server prior to changing to CentOS/iRedMail. I checked DNS with ping (which does not work but that could be because they won't return a ping) and with jwhois and it resolves this address. Any ideas what I may have missed on the install or what might be stopping email from going through? Not sure one email address is an issue but since the server has only been up for 5 days I want to avoid a future problem.
