When using Milter applications for non-SMTP mail: there is no SMTP session. To keep Milter applications happy, the Postfix cleanup server actually has to simulate the SMTP client CONNECT and DISCONNECT events, and the SMTP client EHLO, MAIL FROM, RCPT TO and DATA commands.
When new mail arrives via the sendmail command line, the Postfix cleanup server pretends that the mail arrives with ESMTP from "localhost" with IP address "127.0.0.1". The result is very similar to what happens with command line submissions in Sendmail version 8.12 and later, although Sendmail uses a different mechanism to achieve this result.
