Sender address rejected: not logged in when sending email?

Question

postfix

There was a problem sending an email to an internal address. In response, messages like:

Mail delivery failed: returning message to sender

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]

SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mail.company.ru [ip]: 553 5.7.1 <[email protected]>:

Good people, help me decide. In which case, I am ready to reimburse the labor costs.

Answer 1

Leading questions:
1) From which mailbox (internal domain or not) to which mailbox (internal domain or not) and from where (world, internal network, etc.) the letter is sent.
2) We need a piece of the log.
And so, at first glance:
1) mynetworks = 0.0.0.0/0 - not particularly relevant to the essence of the problem, but at least not safe
2) smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/whitelist, reject_sender_login_mismatch , permit_sasl_authenticated - try remove selection
