When sending out email we are getting responses after 48 hours that they are not delivering. No action is needed on our part. Sometimes they eventually send but this isn't working as we need emails to be sent right away. Not sure what the issue is. Here is an example:

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 48 hours on the queue on se2-iad1.servconfig.com.

The message identifier is: 1jv2ik-0016fk-9e
The date of the message is: Mon, 13 Jul 2020 11:58:27 -0600
The subject of the message is: Elder Agenda

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

bobcatphipps@msm.com

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.
