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. ;-)
