Anybody else getting too-many-bounces warnings from the list today, or is it just me?
I got a total of 40 suspension notices today, all of which were gmail accounts. I’ve re-enabled them all.
They all looked like this:
SarekOfVulcan@gmail.com: host gmail-smtp-in.l.google.com[209.85.201.27] said: 550-5.7.1 Unauthenticated email from pegasus.co.uk is not accepted due to 550-5.7.1 domain's DMARC policy. Please contact the administrator of 550-5.7.1 pegasus.co.uk domain if this was a legitimate mail. Please visit 550-5.7.1 https://support.google.com/mail/answer/2451690 to learn about the 550 5.7.1 DMARC initiative. p142-v6si1992073qke.108 - gsmtp (in reply to end of DATA command)
The problem seems to be that gmail doesn’t like Paul Newton’s ISP (pegasus.co.uk), and actively blocks emails with that From address. Paul, maybe you might like to educate your ISP about DMARC. ;-)
