Analysis Sending of Email
Your mailserver does not use SNI, hence does not support RFC 7672 nor RFC 8461, and likely accepts any certificate when sending (bad).
Your mailserver was sending a mail (FROM/RCPT/DATA) without using STARTTLS first. Even though it may support RFC 7672 or RFC 8461, it does not enforce encryption (bad, but kind of normal).
Your mail server does not support DKIM (bad).
Your mail server does not support DMARC (bad).
