currently spf record of both domains are the same:
"v=spf1 a mx ptr ptr:sendingdomain1.com ptr:sendingdomain2.com ~all"

Might PTR causing issue because of it is deprecated?

Hello,

I have configured server to support 2 sending IP addresses with corresponding 2 
sending domains.
DKIM, SPF, reverse hostname works correct, primary and secondary instances are 
setup with
corresponding myhostname and smtp_helo_name. smtp_bind_address also configured 
correct on both
instances. But for some reason Gmail or Microsoft Outlook detecting second 
domain as spam but first
one working well. How to debug this? I can provide any details if needed.

Best regards,

do your spf record(s) specify both IP's? Maybe the 2nd domain uses the wrong IP 
as per your SPF record?
