Email Policy on arnor.org

Most of these rules are only the direct application of the rules described in the RFCs. Please take note that some of your mails may pass through even if some of these rules are not applied because we are using an advanced whitelisting system which works one a "one sender and one recipient" basis. This system permits some mails to pass through if they are replies. In no case this garantees you that all your mails will pass through if you do not follow the basic rules for sending emails.

"The Internet relies on the cooperative use of private resources. Sending email is a privilege, not a right."
