Add email authentication to Google Workspace account to reduce being filtered as spam/junk

[wang-arthur]

Some of our outgoing emails (to authors and potential peer reviewers) are getting filtered out as spam/junk. We can reduce the incidence of this by setting up the recommended email authentication methods listed here: https://support.google.com/a/answer/81126 (these are recommended for INCOMING messages to Google -- they will likely help with outgoing mail too, but shouldn't they already be implemented?)

Instructions from the link above

• [ ] Set up SPF or DKIM email authentication for your domain.
• [ ] Ensure that sending domains or IPs have valid forward and reverse DNS records, also referred to as PTR records. Learn more
• [ ] Use a TLS connection for transmitting email. For steps to set up TLS in Google Workspace, visit Require a secure connection for email.
• [ ] Keep spam rates reported in Postmaster Tools below 0.10% and avoid ever reaching a spam rate of 0.30% or higher. Learn more about spam rates.
• [ ] Format messages according to the Internet Message Format standard (RFC 5322).
• [ ] Don’t impersonate Gmail From: headers. Gmail will begin using a DMARC quarantine enforcement policy, and impersonating Gmail From: headers might impact your email delivery.
• [ ] If you regularly forward email, including using mailing lists or inbound gateways, add ARC headers to outgoing email. ARC headers indicate the message was forwarded and identify you as the forwarder. Mailing list senders should also add a List-id: header, which specifies the mailing list, to outgoing messages.
