BAYES_50. It is a Bayesian filter rule. It considers 50% that the email is SPAM, based on the subject and content of the message itself. 50% is not much, therefore it only scores 0.8 points. It is not a failure as such and almost does not affect the score.
HTML_MIME_NO_HTML_TAG. The mail has been sent in HTML format, but it does not include the own tags of the HTML code The failure is caused by the program with which the mail is sent. We recommend updating the program. It is a mid-level failure, it should be corrected to ensure that the recipient does not mark the email as Spam
MIME_HTML_ONLY The mail was sent in HTML format and does not include a text-only version. A Content-Type: multipart/alternative must be submitted; The failure is caused by the program with which the mail is sent. We recommend updating the program.

SPF_NONE The sender’s domain does not have an SPF record. The SPF record is a registry that is added automatically when we create a hosting account, it serves to legitimize a client. If that email was sent without SPF, it is very likely a spammer. It is a critical failure, the mail should not be sent like this, that’s why it has been scored 4 hit points. Even if the mail had not been blocked by our relay, the recipient would surely have marked it as SPAM and the reputation of our server would have been penalized for future shipments.
Less than 0.3% of the emails sent by our clients are incorrectly marked as SPAM.
In these cases, we provide the necessary information to correct the problem in the bounce email.
