postfix uses the verified hostname, as explained at

if you are sure that ip -> name and name -> ip mappings match, you should check if your smtpd runs chrooted and the files in the jail were updated correctly.

Yes sounds like the files in the chroot may not have updated. Where are the chroot DNS files postfix uses?

Thanks!
