Dear Sir,

Follows your advice, I remove "smtpd_access_maps" from "parent_domain_matches_subdomains", now, postfix knows the initial dot for
subdomains.

It run very good.

Thanks you very much.

Like access(5) says, domain.tld will match subdomains if
smtpd_access_maps is listed in parent_domain_matches_subdomains.
Otherwise, .domain.tld can be used to match subdomains.

Ergo, remove smtpd_access_maps from parent_domain_matches_subdomains.
