Nope. Postfix shuffles equal-weight MX records internally, so it
doesn't matter what order the NS presents them. Multiple A records
without an MX record (or when MX lookups are suppressed) are treated
as equal-weight MX records per RFC.
This is likely a postfix configuration problem. The original poster
should seek further help on the postfix-users list.
