I have a problem (BIG PROBLEM) with SPAM.

All the emails my mail server (Debian 8.2 and ispconfig latest stable) send, end up in spam. I'm using Google Apps.

I did a test on spamscorechecker.com and the error message is:

  • 0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid domain

My domain is ambrabaiocchi.it (with valid DKIM and SPF record) and more 3

For more info please check this: https://www.mail-tester.com/web-G3h54I and this: http://www.lucavasini.it/output.rtf.

How can I solve the problem?

Thanks and sorry for my bad english.

The problem is related to be missing spf record for Google Apps as described here: Prevent your Google Mail from Getting Rejected as Spam

One needs to add a spf record to the domain example.org to authorize google apps mail server to resolve the issue:

v=spf1 include:_spf.google.com ~all

The entry _spf.google.com means that any server that is allowed to send mail from the IP addresses of Google Apps mail servers is also allowed to send mail from example.org. The ~all directive means that email messages that are not sent from an approved server should still be accepted but may be subjected to greater scrutiny.

Here is how to add it: Configure SPF records to work with Google Apps
