Hey! My opensmtpd server is up and running and so far has worked quite well. But suddenly when trying to send an email to a particular address I got the error message:
550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1) Does anyone know what could be the cause of this? My config: ` pki bitpuffin.com certificate "/etc/ssl/certs/mailcert.pem" pki bitpuffin.com key "/etc/ssl/private/mail.key" listen on enp0s3 tls pki bitpuffin.com listen on enp0s3 port submission tls-require pki bitpuffin.com auth accept from any for domain "bitpuffin.com" deliver to maildir accept for any relay ` Best regards, Isak Andersson
