And the is the same IP that i have on my "default_bind_address" postal.yml parameter.

I can use Postal normaly, but every 3/4 minutes logs give me this errors.

Does anyone knows why is this happening?

Thanks for your help !

Is it possible you have MX records pointing at Postal so it is essentially trying to send itself a message?
