One more comment -- I looked at how emails were being handled by my outside SMTP server and found this information:
05/22/2020 15:01:57 Delivered mxbackup1.clearsdn.com [159.203.59.228]
250 2.0.0 Ok: queued as CBBD240FDA (delivered to geep@wa4rts.net)
05/22/2020 15:01:57 www.wa4rts.net [73.147.60.131] Connection timed out
05/22/2020 14:59:46 Processed localhost Received by mail.smtp2go.com (Mailer-Daemon@smtpcorp.com -> geep@wa4rts.net)

So my comcast address is being queried and timing out. If I could solve why this is happening, this issue would be fixed. Any ideas? Is Comcast blocking the connection?
