Email Has Stopped Working
Email has worked fine for nearly 10 years but is has recently stopped working. It still receives incoming email but all outgoing gets this Mail Delivery System failure message:
"This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
host gmail-smtp-in.l.google.com [18.104.22.168]
SMTP error from remote mail server after end of data:
