    I am having an issue on one of my vps that we are not getting mail from external domains (like gmail,yahoo, or any other domain). Mails are going successfully from the vps but no domain is receivng mail from outside domain. In exim_main log it is showing below errors.

    2013-01-17 02:17:28 unknown named host list "+rv_relay_hosts"
    2013-01-17 02:17:28 unknown named host list "+rv_relay_hosts"

    And sender is getting this error: R=dkim_lookuphost T=dkim_remote_smtp defer (-44): SMTP error from remote mail server after RCPT TO:: host [VPS IP]: 421 Unexpected failure, please try later.

    Can anyone please help to resolve this issue.
