i have these errors on mxtoolbox.com, 1 SMTP Reverse DNS Mismatch 2 SMTP Valid Hostname what is the solution?
you have 2 reverse dns for the MX if you have 2 MX asigned diferents valors in Priority in MX SPF u can use opendkim for configure your ip.Gmail also requests spf data to send emails managed by them but gmail have good faq for this.Also you can use postfix-policyd-spf-perl with postfix-policyd-spf-python

i'm not sure what is MX, you are very smart, i have set 2 rDNS for 2 different IP's to the same hostname , is this what you mean? and how to use opendkim or postfix-policyd-spf-perl with postfix-policyd-spf-python thank you very much, you are my superman :)
ok i had to enter SPF and DKIM plus DMARC in DNS manager
