Issue Mail forwarding - 553 sorry

[A.Mason]

Sorry for my english.

When i enable forwarding in mails configuration panel in Plesk and add address from external domain, then i got mail delivery failure. For mails from my own domain all is OK.
How fix that problem without losing security?
I have Postfix with Dovecot

I think this problem is addressed in the following KB - https://kb.plesk.com/en/168 Does this solve your issue?

Thx for replies. I think my problem is similiar, but occurs not when some person sent mail. I have errors only when i set forwarding to external email in in e-mail setings in plesk panel (domains -> emails).

Anybody can help? I think this is problem in headers configuration forwarding machine. In the mail is given the original sender, but with my server IP. I don't now what i must reconfigure and how?
