I’ve noticed a weird issue with my email setup. About 10% of my messages don’t pass SPF alignment in DMARC checks. It’s strange because they still get delivered most of the time. Only once did I have a problem when someone using Mailgun didn’t get my email.
I really want to fix this alignment problem. The emails are getting authenticated, but they’re often not aligned. Any ideas what might be causing this? I’m using Gmail as my email service.
Has anyone else run into this? What steps can I take to troubleshoot? I’m worried this might cause more delivery issues in the future if I don’t sort it out soon.
I’ve been there, mate. SPF alignment issues can be a real pain. In my experience, the problem often lies with email forwarding services or using multiple email platforms. Have you checked if you’re using any email forwarders? They can mess with the envelope sender and cause alignment failures.
Another thing to look at is your DNS records. Make sure your SPF record includes all the IPs and domains that send emails on your behalf. I once spent days troubleshooting only to realize I’d forgotten to add a new marketing platform to my SPF record.
If you’re using Gmail, they sometimes modify headers which can lead to alignment issues. You might want to consider setting up DKIM signing directly on your domain instead of relying on Gmail’s. It’s a bit more work, but it can help with these alignment problems.
Lastly, don’t forget to check your DMARC reports regularly. They can provide valuable insights into where exactly the alignment is failing. Good luck sorting it out!
This issue often stems from email forwarding or using third-party services that modify the envelope sender. Gmail, for instance, can sometimes cause SPF alignment failures when sending through their servers. To troubleshoot, I’d recommend checking your email headers to identify where the alignment is breaking. Look for discrepancies between the ‘From’ address and the ‘Return-Path’. Additionally, consider implementing DKIM if you haven’t already, as it’s generally more resilient to forwarding. Lastly, review your DMARC policy - you might want to start with a ‘p=none’ policy and gradually increase enforcement as you resolve alignment issues.
hey there! i’ve dealt with similar SPF issues before. it could be that your SPF record isn’t including all the servers sending mail for your domain. maybe check if you’re using any third-party services that send on your behalf? also, make sure your ‘from’ address matches the sending domain exactly. hope this helps!
