Your service provider is now using MailChannels Outbound Filtering to send email from the hosting server on which your account is located. Correct Sender Policy Framework (SPF) records need to be configured in your DNS settings to ensure that Internet receivers will properly identify and receive your email. This article describes the DNS records you must add.
DNS Records
The following records are needed for SPF to work correctly. Replace example.com with your own domain name:
Location |
Type |
Value |
example.com |
TXT |
v=spf1 a mx include:relay.mailchannels.net ?all |
|
If you already have an SPF record, simply add include:relay.mailchannels.net to this entry. Make sure to add it BEFORE the “all” mechanism as “all” always matches and typically goes at the end of the SPF record.
Note: DKIM keys can be added for Cpanel using our Cpanel - DKIM Configuration Guide.
cd /var/cpanel/users
for i in `ls /var/cpanel/users` ;do /usr/local/cpanel/bin/spf_installer $i ;done
Note: Please test this thoroughly before implementing this on production servers
Next Step: Set up monitors
Do you know how to "mass add" these records to existing domains? I'm running cPanel, but that shouldn't make much difference. All the domains already have their own SPF records.
I am having the same question as "WebHostingZone"
Messages that are signed via DKIM, and that get passed through your relay servers are getting munged. Making the digitally signed messages (and headers) appear as tampered with or spoofed.
Why not use the stricter -all rather than ?all. I like to use -all so that mail servers paying attention to spf will not accept spam from compromised machines forging my addresses.
And is there a WHM or cPanel plugin that automates this task every time a cPanel account is created or a new domain is added?
