Regarding the recent "Important Notice About Your Email Service" noting that Google will be "requiring that all email senders which send over 5,000 messages a day must have a DMARC policy and ensure all email is properly aligned with DKIM and SPF." - I send email through Postfix on my machine, using sonic as the relayhost. AFAICT my mail as seen by receipients has Sonic-inserted DKIM headers. Should I expect to be unaffected by this latest move to make email into a walled Google garden?
Also, does "email senders which send over 5,000 messages a day" refer to Sonic itself, or to individual users?
