Configure SPF record for multiple email domains hosted on a single server

We use Kerio mail server for multiple email domains, with separate IPs for each domain. We also use Windows SMTP service for sending mails from an application(say, email domain is domain A with IP A). Kerio SMTP service is listens to IP B, and domain B in Kerio  is linked to IP B.

When I send mail from domain B, the source IP is displayed as IP A. I configured SPF record for domain B and when I tested that, I found this.

Would appreciate if anyone can advise me on what is the correct configuration

When you send mail, it's going to come from the primary IP address, no matter what IP that domain is listening on. This isn't a big deal, and I would probably just add all the IPs to the SPF record for each of the domains.

"v=spf1 ip4:1.2.3.4 ip4:1.2.3.5 ip4:1.2.3.6 ip4:1.2.3.7 -all"

Thank you.
It is not about SPF alone. I want the mails from different domains to go from different IPs.I think bacause of the volume of mails from a single IP, we get greylisted, our mails to Yahoo get dalayed, go into spam folder, sometimes don't get delivered at all.
Mail server has an option of binding the domain to a specific IP adress... will the mail go from the primary IP, even then?

I'm pretty sure even if you bind it to a specific IP, it'll use the primary for sending. I know with Sendmail on Linux you can create multiple instances of Sendmail on specific IP addresses, but it sounds like you're using windows; I don't know if you can do that.
