Subject: Warning: message 1XgcAj-0002Wq-2s delayed 24 hours

This message was created automatically by mail delivery software.
A message that you sent has not yet been delivered to one or more of its
recipients after more than 24 hours on the queue on bosmailout03.eigbox.net.

The message identifier is:     1XgcAj-0002Wq-2s
The subject of the message is: FW: Marker Layout
The date of the message is:    Tue, 21 Oct 2014 09:19:31 -0700

The address to which the message has not yet been delivered is:

  rmorgan004@ca.rr.com
    Delay reason: SMTP error from remote mail server after initial
connection:
    host cdptpa-pub-iedge-vip.email.rr.com [107.14.166.70]:
    421 4.7.1 - Connection refused - <66.96.184.3> -  Too many concurrent
connections ( <2> ) from source IP

No action is required on your part. Delivery attempts will continue for some
time, and this warning may be repeated at intervals if the message remains
undelivered. Eventually the mail delivery software will give up, and when
that happens, the message will be returned to you.
