Can't seem to relay my email via postfix. I followed your tutorial and it does not work. Here is what I get back (I x'ed the actual email address):
2020-11-18 16:06:41.434423-0500 0x8cfcd Info 0x0 59305 0 smtp: BFBC23FE8080: to=<xxxx@xxx.org>, relay=relay.dynu.com[168.235.95.80]:587, delay=0.65, delays=0/0/0.49/0.16, dsn=5.0.0, status=bounced (host relay.dynu.com[168.235.95.80] said: 530 SMTP authentication is required. (in reply to RCPT TO command))

Any thoughts?

Thanks
