Please check if the settings of d-thinker email system is all good so that nobody would mistake us as a spurious email system.

I just sign up an account on Yahoo and send email to amoners at d-thinker.org. Both send and receive email between d-thinker.org and yahoo.com are work for me. And I checked that there are no specify setting for yahoo expect a rule set yahoo.com in white list.

Could you provide more details?
