Zimbra mail reception error

[princebenin]

Hi.

I installed a Zimbra server. All functions well
except that I cannot receive mails. I can sent.
Here are data:
OS Server: Debian 3.1
hostname or hostname - f: both ==> mail.mydomain.org
dig mx mail.mydomain.org ==>
;; ANSWER SECTION:
mail.mydomain.org. 432000 IN MX 0 mail.mydomain.org.
;; ADDITIONAL SECTION:
mail.mydomain.org. 432000 IN A XX.XX.XX.XX

the only error worrying in the log is as follows:
May 23 09:12:51 mail postfix/trivial-rewrite[14633]: warning: do not list domain mail.mydomain.org in BOTH mydestination and virtual_mailbox_domains
telnet on "mail.mydomain.org 25" ==> greeting banner ::
220 mail.mydomain.org ESMTP Postfix

Can you help me please?

First, if you want to send mails to user@mydomain.org, your MX record should look like this:
mydomain.org. 432000 IN MX 0 mail.mydomain.org.(no mail part).

the only error worrying in the log is as follows:
May 23 09:12:51 mail postfix/trivial-rewrite[14633]: warning: do not list domain mail.mydomain.org in BOTH mydestination and virtual_mailbox_domains
telnet on "mail.mydomain.org 25" ==> greeting banner ::
220 mail.mydomain.org ESMTP Postfix

Remove mail.mydomain.org either from mydestination or from virtual_mailbox_domains in /etc/postfix/main.cf and restart Postfix.
