What (and why) do you have smtpd_client_event_limit_exceptions set to?
Also, I don't believe for a second that domain.com is connecting to you.
Dr. Wietse,
Thank you very much for taking the time to reply to my email.
I enabled TLS on Postfix with a certificate from letsencrypt.com for
temporary solution. This solved the problem, we're now able to received
emails from that specific client.
Your support on this matter is appreciated

support.
Which is not in itself a bad thing. The only thing broken about this IF
it's because they require TLS
