An MX record is not required by RFCs, a single A record should be tried if there are no MX records. And the sending server's PTR doesn't have to match its hostname(s), nor the domain in the email address

The only validation you should be doing before sending the message is
on the domain part. Since there are records available in DNS to
verify, you can check those. Is there an MX record? Is the address
valid? Do the mappings both way for that record make sense?
