Hello.
I was able to replicate this error, however it's not a misconfiguration
in Postfix, but rather a policy change by Google. I didn't notice the
bounce message sooner, since it was routed to my SPAM folder on Gmail.
If I use a GMAIL From: address and attempt to email another GMAIL
I might had used the wrong terminology. I was mainly referencing delayed
email that occurs with Grey listing. Most of the delay email for me is
either Google or Yahoo.

Hi Kevin.
If the delays are being caused by bounce message processing, you could
run a second instance dedicated to just processing delayed messages
using fallback_relay.
You can also make adjustments to the individual queues in master.cf, one
tweak I use is increasing the flush rate to
Hello.
Some alternatives might be to use one of the commercial bulk mail
providers such as:
Sendgrid

MailGun
I use mailersend.com for transactional emails for Reverse.net. Other
options include buying a $5 KVM and self hosting a public relay for

Hello.
It really depends on your mail volume and the reliability of your
primary MX hostname. Typically the RFC permits mail to be delayed for up
to 5 days at which mail will bounce back as undeliverable. For most
low-volume sites, a primary only MX configuration is fine.
Both of those

You can try adding to your main.conf:
tcp_windowsize=65535

That can help fixing broken window sizes because of a firewall.

Hello.
I found the issue. It seems I had the list address saved as a contact,
so Thunderbird was displaying Postfix Users. I removed the contact and
it's displaying the poster name.
See screenshot.
Thank you.

Hello.
Sadly, when viewing this list in Thunderbird, it only displays "Postfix
Users" as the From address, versus showing the posters name. I tend to
ignore posters I don't recognize, and now i need to open each post to
see who replied.
Any workarounds in Thunderbird to override this
