The mail/rcpt/data commands were pipelined together, and all three were rejected, then the remote client issued RSET and QUIT, but RSET was also rejected! The only way that RSET is rejected (barring unlikely syntax errors) is indeed if you're enforcing TLS, which would also explain why mail/rcpt/data were rejected. -- Viktor.
