Hi
Your test domain check.smtpsmuggling.com has a neutral SPF record, but no MX record, so many mailservers will reject it (eg. with postfix reject_unknown_sender_domain). Can you add an MX record as well please?
reject_unknown_sender_domain
[DEBUG] (1, {'code': 450, 'message': '4.1.8 <setup_check@check.smtpsmuggling.com>: Sender address rejected: Domain not found'})
Thanks for the feedback! I've added MX and A records. Please retry!
Works now, thanks!
