Whitelist the client before the check that would otherwise
reject them.

In this case:
# main.cf
smtpd_helo_restrictions =
check_client_access hash:/etc/postfix/client_whitelist
reject_non_fqdn_hostname
reject_invalid_hostname

# client_whitelist
212.49.203.243 OK

Be sure to "postmap client_whitelist" after editing the
whitelist file, and run "postfix reload" after editing main.cf.

Note this client might be rejected by rules you have in smtpd
sender or recipient restrictions. You may need to put the
same whitelist in those restriction lists also.

If you need further help, please post current log entries and
output of "postconf -n"
