Can't send E-mail to yahoo.com
Posted on 2012-09-17
I can't seem to send E-mails to yahoo.com. In the Queue Viewer I get the "last error" message "421 4.4.0 Primary target IP address responded with: "421 4.2.1 Unable to connect." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts."
Any help would be much appreciated.
