From ChangeLog-4.42:
12. RFC 3848 specifies standard names for the "with" phrase in Received: header
lines when AUTH and/or TLS are in use. This is the "received protocol"
field. Exim used to use "asmtp" for authenticated SMTP, without any
indication (in the protocol name) for TLS use. Now it follows the RFC and
uses "esmtpa" if the connection is authenticated, "esmtps" if it is
encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
names appear in log lines as well as in Received: header lines.
