Hi!

I’ve recently set up a Droplet with Ubuntu 14.04 and Zimbra for an educational experience.

Everything appears to be functional, but mail sent from my server is being marked as spam in gmail, yahoo, outlook, zoho. It doesn’t even arrive on my fastmail address.

I’m pretty sure I’ve setup DKIM, SPF, DMARC correctly. The IP is not blacklisted.

SPF:

v=spf1 a mx ~all

DKIM:

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC3PGJuQDhPZs0dcXz+8XbYO+qzL4E1FSXnOkU5G7JtP7wwE3hXwO4QxUgwhSGC8Z75naF57ewcN5brz7Pe1dqM3JXcEo71+bz6rjvXXO2RqU5jcY1gE2+XnHqUQo8A80YmosI9sgnIM7riFnjeyVB/jozxVDH3rPyhLLJ4T2PWLQIDAQAB

DMARC:

v=DMARC1; p=none; sp=none; rua=mailto:overseer@adamdistefanotesting.net; ruf=mailto:overseer@adamdistefanotesting.net; rf=afrf; pct=100; ri=86400

I’ve done some tests from

• mxtoolbox (http://mxtoolbox.com/domain/adamdistefanotesting.net/)
• allaboutspam (http://www.allaboutspam.com/email-server-test-report/?key=C3DEA35D5AD65B799BD6F525CCEE953E)
• mail-tester

and they’ve come back all good.

I really have no idea why my mail is being marked. The headers state that dmarc, dkim and spf are passing.

Any help would be apprecaited!

Cheers
