SenderID/SPF
When you add SPF information to your DNS records, you are able to specify which email servers you use to send email from your domain.This validates your sending email address, which can improve your email deliverability rate. In other words, SPF helps to keep your domain's email out of your recipients' spam folders.
To get started, you must first contact your DNS hosting company and ask them to add the following SPF information to your DNS records. Or,if you can log in to the control panel for your DNS, you can make this change yourself.
Record Type
|
TXT
|
Address
|
v=spf1 [any combination of the below] ~all
|
Toolkit Webmail customers:
|
include:emailsrvr.com
|
Toolkit Broadcast customers:
|
include:md02.com
|
If you send email from your own server (replace "1.2.3.4" with your mail server IP):
|
ip4:1.2.3.4
|
For example, if your domain falls into all of these categories, the SPF would look like the following:
v=spf1 include:emailsrvr.com include:md02.com ip4:1.2.3.4 ~all
Repeat these steps for every domain from which you plan to send emails.Note: When you are composing an email, you must use a "From" address(or, specifically, a "Return-Path") that belongs to a SPF-enabled domain, otherwise SPF will not be in effect.
