Are you sure the word "exception" is there? Postfix does not generate
messages, but it does generate "Domain not found" when a domain does
not exist or has no MX or A, AAAA records.

If you want usable help, you'll need to be willing to post the actual
domain name, not an obfuscated version.

The first line below does not look like a valid PCRE table pattern.

You really should write:
smtpd_sender_restrictions =
check_sender_access hash:/etc/postfix/access,
check_sender_access pcre:/etc/postfix/no_a_record.pcre,
reject_unknown_sender_domain
but again, post the output of "postconf -nf", being careful to
not fold any lines, or otherwise add or remove whitespace.
Do not send HTML email, compose it as plain text.

Post the *actual* domain name in question. Also your "postconf -nf"
output as requested above.
