Sometimes, for various reasons, you may need to make a scanning exception for SPF on your Plesk server, this can be done by doing this:
Go to Plesk Control Panel –> Tools & Settings –> Mail Server Settings.
Add ip4:x.x.x.x or include:domain.com to the SPF local rules field.
More than one entry should be separated by spaces.
Click OK.
And that’s it! 🙂
Hi,
I’ve tried:
include:domain1.com domain2.com domain3.com, and
include:domain1.com include:domain2.com include:domain3.com
but both are not working.
Appreciate your advise.
Thanks & regards

Hi,
Due to this:
https://docs.plesk.com/en-US/12.5/administrator-guide/mail/antispam-tools/sender-policy-framework-system-linux.59435/
Following rfc4408
Your 2nd solution should be working.
Have you tried rebooting the Plesk server to make sure the SPF settings get implmented correctly?
(Sorry for the delay – been on vacation 😉 )
Best regards
