I have just had several email bounces from a mailing list that I have been
running since 2005.
I have contacted Google using this form
<https://support.google.com/mail/contact/gmail_bulk_sender_escalation?visit_id=638474903329581839-3979393277&rd=1>
and gotten a reference number 7-2893000035971.
The strangest thing is that I have gotten only 37 bounces whereas my
mailing list has several hundreds of gmail.com addresses.
The bounce text looks like this:
```
john...@gmail.com
host alt2.gmail-smtp-in.l.google.com [142.251.9.26]
SMTP error from remote mail server after end of data:
550-5.7.1 [41.212.32.14] The IP you're using to send mail is not
authorized to
550-5.7.1 send email directly to our servers. Please use the SMTP relay
at your
550-5.7.1 service provider instead. For more information, go to
550 5.7.1 https://support.google.com/mail/?p=NotAuthorizedError
j21-20020a508a95000000b0056bacdf79e0si3584946edj.443
- gsmtp
```
Now, this server - 41.212.32.14 - is authorized (by ALL DNS requirements
and policies) to handle mail for lists.kictanet.or.ke which is the domain
name used for the mailing lists.
Why would this happen?
Last but not least, I have never seen any data on the Postmaster Tools web
UI. How do you guys set that up so that you get reports/data from Gmail?

In an Internet failure case, the #1 suspect is a constant: DNS.
"Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-)
