Gmail can't verify my server's emails even with SPF and DKIM set up
I feel like I've tried EVERYTHING to get my server's email working. I've been working at it on and off for months. Here's what I've done so far:
Everything looks good, and yet when I send a test email from my server to my Gmail account, it is flagged with the question mark icon and says "Gmail couldn't verify that windhorse.ca actually sent this message (and not a spammer)."
Could it be that I've taken so long to get this working that Gmail has flagged my domain as spam??
