Emails marked as spam - SPF passes, DKIM passes, sender-id passes

Asked 13/8, 2012 at 21:17 Answered 8/1, 2017 at 14:49

I've been struggling to figure out why this is happening, but my emails are being marked as spam by Gmail and Hotmail (they work in Yahoo.)

SPF, DKIM, rDNS, and sender-id all pass. What's weirder is I've send the EXACT same email with its exact contents from my dev server and Gmail accepts it as not spam even though every one of those checks which passes in production fails in dev. Hotmail still marks it as spam though.

Any idea what could be going on? Here is an example header from Gmail (with IPs and domains changed for privacy):

Received-SPF: pass (google.com: domain of [email protected] designates xxx.xxx.xxx.xxx as permitted sender) client-ip=xxx.xxx.xxx.xxx;

The other guy doesn't know what he's talking about and just guessing.

'Received: (from root@localhost)' is your problem. That needs to reflect the from email...

You problem is:

domain: mydomain.com ip: xxx.xxx.xxx.xxx

and root@localhost too

You need change informations in your mail client!

I have the exact same problem. In my case, I have configured my mail client correctly. I have one main domain (mydomain.com), my mail server also supports another domain (mydomain2.com) using virtual_domains. However, the emails for (mydomain2.com) always end up in Spam in Gmail. The mail-tester score for mydomain2.com is 9.7/10. Here is the original header from Gmail (i have replaced IP and email address with example ips)
