These days with big company email, I assume headers are no longer useful. Once it hits Google or Microsoft or whatever, it disappears into the void. Even identifying the original sender is usually impossible. You were lucky in this case to get so much information.
It's like reverse DNS. Half the time there is no rDNS at all, and if there is, usually it just points to a CDN with thousands of customers. -----Original Message----- From: AF <af-boun...@af.afmug.com> On Behalf Of Mike Hammett Sent: Monday, March 24, 2025 10:21 AM To: AnimalFarm Microwave Users Group <af@af.afmug.com> Subject: Re: [AFMUG] Mailing List Rate Limiting or Having Issues? I do use O365, but not for this. This is all on my own infrastructure. The link on the original email showed each hop the message went through on the way from me back to me and how long each hop took. -- Mike Hammett ----- Original Message ----- From: "Adam Moffett" <dmmoff...@gmail.com> To: "AnimalFarm Microwave Users Group" <af@af.afmug.com> Sent: Monday, March 24, 2025 10:17:57 AM Subject: Re: [AFMUG] Mailing List Rate Limiting or Having Issues? Are you using O365? I've been seeing issues with Outlook and Sharepoint this morning. According to downdetector.com I'm not the only one.

If it's a rate limit because I sent so many messages at once, I understand. I sent about 10 - 15 messages to the list over 1.5 hours. I mean, it's not a LOT lot, but it's more than normal. -- Mike Hammett ----- Original Message ----- From: "Chuck" <ch...@go-mtc.com> To: af@af.afmug.com Cc: af@af.afmug.com Sent: Sunday, March 23, 2025 5:40:23 PM Subject: Re: [AFMUG] Mailing List Rate Limiting or Having Issues?
