Any way to turn off SPF checking on Plesk for a specific IP?

[minhnv]

I want to reject all email traffic from the internet except those as below can send mail to my Plesk server :
+ my antispam ( smarthost ) with IP ( a.b.c.d )
+ all my user in the plesk server with authentication


So i plan to set SPF checking on to Reject mail if SPF does not resolve to pass but

1. can't find option to whitelist my smarthost IP
Is that option Local Rule: " v=spf1 ip4=a.b.c.d -all " can resolve my problem ?
2. all of my user do not affected by the "Reject mail if SPF does not resolve to pass " right ?

Please help me. Thank you in advance!!

Yes, it should be local rule.
It is "ip4:a.b.c.d". You should also specify "mx": https://tools.ietf.org/html/rfc7208#page-23

Please take look on examples: https://tools.ietf.org/html/rfc7208#page-55

As for SPF check results processing - it is up to you, "Reject mail if SPF does not resolve to pass" is strongest: https://tools.ietf.org/html/rfc7208#appendix-G.1
