[conspire] (forw) IP reputation of 96.95.217.99, pacbell.net's NDR

[Rick Moen]

Mailing lists are inherently caught in the middle of the decades-long
spam war.  Sometimes, even if you do everything right, some mail
provider blacklists you for dumb or inexplicable reasons.  Seems like
pacball.net recently did this to my linuxmafia.com server IP.

I may or may not get corrective action (or explanation).

Organization: If you lived here, you'd be $HOME already.

Dear NOC staff:

I'm owner/operator of linuxmafia.com, IP address 96.95.217.99, and
have carefully run a clean, reputable mail operation for about forty years.
It includes GNU Mailman mailing lists, such as the one your customer
Walter Young <walyou at pacbell.net> joined.  I see that your MTA is now 
refusing the regular monthly password-subscription reminder to Mr.
Young (generating the non-delivery report below), and I am mystified
about why.

As I regularly do, I just checked my IP's RBL reputation at the
multi-RBL engine at https://multirbl.valli.org/ .  247 RBLs are checked.
In this case, 243 reported green (not listed), four failed to answer,
and there were no blacklistings.

Multi-RBL site https://www.dnsbl.info/ likewise reports all green.
https://mxtoolbox.com/blacklists.aspx shows 82 greens and one timeout.
https://whatismyipaddress.com/blacklist-check shows all green.

May I ask, what is the basis of AT&T / pacbell.net's refusal?  Is there
a complaint?  I will be glad to address & remedy any complaint I can.
