I have a certain user that I try to send mail to on an Earthlink domain and receive this error...
RCPT TO <[EMAIL PROTECTED]> failed: <[EMAIL PROTECTED]>: Recipient address rejected: unverified address: connect to mx00-dom.earthlink.net[207.217.125.16]:25: Operation timed out As you can see, we do address verification, but the problem appears to be timing out. But I send to another user on the same domain and the message goes out without delay both before and after this error. I looked up this other user message in the logs and their address was verified OK and used the same IP address for successful delivery. What does this tell me? -- Robert
