Hello Habib,


Thank you for writing to the Sender ID Management Team. This is Maybelle and I understand that you would like to have your ***.com, ***.com, ***.com and
***.com domains to be added to the Sender ID program. It is a privilege to provide you assistance on your concern.
We have added your ***.com, ***.com, ***.com and ***.com domains to the Sender ID program. This may take up to 2 business days to be fully replicated in our systems. If you have any questions regarding this please let me know.

However, we have reviewed the SPF record of your e****.com domain and note that it includes the "ptr" or reverse DNS lookup mechanism. The specification for SPF records (RFC 4408) discourages use of "ptr" for performance and reliability reasons. This is especially important for Windows Live Mail, Windows Live Hotmail and other large ISPs as a result of the very high volume of mail we receive each day. We highly recommend you remove the "ptr" mechanism from your SPF record and, if necessary, replace it with other SPF mechanisms that do not require a reverse DNS lookup, such as "a", "mx", "ip4" and "include." This will help ensure that Sender ID validation is performed as accurately as possible, maximizing your email deliverability while protecting your domain from spoofing.

You do not need to notify us when you make this or any revision to your SPF record since we will automatically pull the current record from the DNS daily. You can find technical information on the Sender ID program at:
Sender ID Home Page

Thank you for your support in improving online trust and confidence and for the interest that you have shown in enrolling to Sender ID.

Sincerely,

Maybelle C.
Sender ID Management Team
