In the specific case of "Relay access denied" it will always
be the recipient address, but there are other reasons for mail
to be rejected.
That section of the log line shows "what" was rejected along
with a brief text description/reason.
The "what" can be any part of the SMTP envelope; client, HELO,
sender, recipient, or in the case of header/body checks, the
text that matched the rule.
