Configure DKIM and SPF for Workplace

You'll need to adjust your DKIM and SPF configuration correctly to ensure mail servers can verify it was you who sent the emails.
Workplace requires that all email replies be sent with DKIM (DomainKeys Identified Mail) or SPF (Sender Policy Framework) alignment. These are industry email security standards that help verify a sender's details, thereby protecting employees from spoof emails. Emails failing these checks are often treated as spam.
To configure DKIM and SPF, please contact your IT administrator with the below information:
Configuration of DKIM and SPF depends on your email server, and your domain's DNS provider. You must have either DKIM or SPF alignment; you can't have both.
For G Suite, follow this guide.
Note that G Suite defaults to its own DKIM signing domain. As this default action will fail DKIM alignment, since the mail isn't signed by your domain, but by a third-party domain, we will still reject your incoming emails. Therefore, you must configure your own DKIM set up.
For Microsoft Office 365, follow this guide.
Learn more about these security standards.
Note: If DKIM and SPF aren't configured correctly, Workplace will reject messages you send for group activity, for example, group posts or comment replies. In the event that this happens, the sender will receive a bounce message, either from Workplace or from other services including Gmail.
