Hi Russ & Udeme,
I'm not sure who Russ and Udeme are, but you've written to a relatively large mailing list.
We also are seeing “554 5.7.1“ bounces from “tds.net, q.com" for the financial communications we send on behalf of our clients.
5.7.1 means that the mail is being rejected deliberately by policy. This is usually due to spam being received.
Knowing the source IP address from which the mail was sent would be useful.
Do you have any contacts , so that we can determine the cause of this.
Did you try postmas...@tds.net and postmas...@q.com ? -- Jay Hennigan - j...@west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
