Mail forwarding problem. How to fix?

Question

Mail server

Good afternoon.
For the mailbox on the Postfix server, I configured incoming mail redirection according to the scheme
[email protected] -> [email protected] -> [email protected]
It works, but if domain1.com=domain2.com, i.e. it turns out
[email protected] -> [email protected] -> [email protected] ,
then delivery to [email protected] is not performed, and [email protected] receives an authorization error from the MYDOMAIN.com server on the domain1 server. com . Why does he ask for authorization - I do not understand.
I use system:
CentOS Linux release 7.3.1611 (Core)
MySQL: Mariadb-server 5.5.52
web-server: Nginx 1.10.2
iRedMail-0.9.6 MARIADB edition
iRedAdmin-Pro-SQL-2.6.0
Already tried to configure redirection through:
1) iRedAdmin-Pro in the Forwarding section;
2) iRedAdmin-Pro in the BCC section;
3) in the mailbox client interface;

4) via SQL server, adding/editing the vmail.alias table yandex), then the redirect works, but if it's a private or corporate mail server, then it doesn't.
What could be the problem?
PS: I have been working with postfix and iredmail quite recently, I will be grateful for any hints.
For a forwarded email that was additionally stored in the forwarding mailbox, the following events are recorded in the /var/log/maillog log:

Answer 1

In order for everything to work, you need to change the domain1.com settings In the message header, the server sees the sender, sees that he is his, that is, from domain1.com and therefore requires authorization. Is there an error "Recipient address rejected: Policy rejection not logged in" ?
