A few days ago I could send emails just fine. Now all the sudden I can not send emails. I just get the error below:
Jan 27 05:25:14 frontier postfix/smtp: C291A6801DF: to=<@.org>, relay=none, delay=0.03, delays=0.02/0.01/0/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=*.org type=MX: Host not found, try again)
Something about MX. I can get emails just fine.
