Anybody know how to contact talktalk.net ? (A British ISP well known for lack of technical support capability.)
I'm getting bounces from them because they've enabled DMARC with p=reject, without setting up DKIM. Consequently any simply re-sent message without header munging (e.g. my organization mailing lists) gets bounced by people who honour DMARC. I tried postmas...@talktalk.net - bounces no such user. I tried the technical contacts in the DNS, doma...@talktalkplc.com . That bounces because it goes to the likewise well known mimecast, who re-send it to microsoft hosted addresses while breaking my DKIM signature, so microsoft bounce it. I am loath to complicate a simple setup by adding header-munging just in order to allow people with crap providers to send mail to our lists ....
