E-mail Issue - Deferred: Connection timed out

Hello. I have one member that is having difficulty with sending e-mails to our club’s e-mail addresses.
We have attempted to use our addresses (i.e. admin@pstoastmasters.org) and the core addresses
(i.e. admin-8591@toastmastersclubs.org).
When she sends attempts to send an e-mail, she receives a message from her e-mail provider saying
that the connection timed out.

I have attempted to adjust the spam criteria and the white list, which helped for a while. However the
issue has now returned.
I’m at a lost for providing additional assistance to the member. I believe it might be an IP issue,
but not sure if it is with FTH or her provider.

The member’s e-mail address is: Karen.Brice@umb.com

Below is an example of what she is receiving:

From: Mail Delivery Subsystem <MAILER-DAEMON@toc-proofpoint.sec.umb.com>
Sent: Thursday, October 31, 2019 8:57 PM
To: Brice, Karen
Subject: Delivery delayed:Testing #1. 10/31 @ 4:48PM


This is an EXTERNAL email. Do not open attachments or click on links unless you have confirmed
