docker-mailserver: cannot update mailbox /var/mail/amavis for user amavis. destination /var/mail/amavis is not owned by recipient

Hello:

My Mailserver could be started up with SSL already, but there still some warning be pushed out like below:

mail    | Aug 12 19:37:56 mail postfix/qmgr[948]: C7CC82015100: from=<amavis@mail.esradio.cc>, size=893, nrcpt=1 (queue active)
mail    | Aug 12 19:37:56 mail postfix/local[26913]: warning: specify "strict_mailbox_ownership = no" to ignore mailbox ownership mismatch
mail    | Aug 12 19:37:56 mail postfix/local[26913]: C7CC82015100: to=<amavis@mail.esradio.cc>, orig_to=<amavis>, relay=local, delay=296380, delays=296380/0.04/0/0.04, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/amavis for user amavis. destination /var/mail/amavis is not owned by recipient)

and my DNS configuration is, because I use DDNS and my 80 port is blocked, some configuration is different with the recommended configuration. Especially I use the DDNS domain for mail.xxx.ltd by CNAME. I dont know if this is right but it works.

So, is anythong wrong with my DNS configuration? or mailserver configuration? How to clean up this message?

Another thing about amavis is i found amavis seems been reseted some time. But I reboot the mail server last day to see if this could be reproduce, but unfortunately, could not be reproduce today.
