postfix reject message problem. Is it my problem or other's mail server?

Hi,

i having the following error in the mail.log log file.

Aug 30 11:40:53g postfix/smtp[18167]: 3EE79836A7: to=<mail@example.com>, relay=mail.example.com[1.2.3.4]:25, delay=79, delays=76/0.14/1.9/0.43, dsn=5.7.1, status=bounced (host mail.example.com[1.2.3.4] said: 553 5.7.1 <myuser@myvirtualmindomain.com>: Sender address rejected: not logged in (in reply to RCPT TO command))

Does anyone know who's fault is that? Is my mail server the problem or the receipient's mail server ?

Plz help.
