which has priority settings, main.cf or master.cf?

[vod vos]

Hi,



We can configure these in main.cf





smtpd_recipient_restrictions = 
permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination,check_poli
    cy_service 
unix:private/policyd-spf,reject_invalid_hostname,reject_unauth_pipelining,reject_non_fqdn_sender,reject_unknown_sender_domain,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,ch
    eck_recipient_access hash:/etc/postfix/recipient_access





And can overwrite parameters=value in master.cf like;



below smtp...smtpd/postscreen or sub..mi.ssion...smtpd



-o 
smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject



which has priority setting?



Thanks.
