See below for explanation of email flow through log file.
The transactions in the log when an email is received and processed to a local user with no errors:
03:19 03:22 SMTPD(00180250) [192.168.1.131] connect 209.221.59.70 port 2539

At this point your mail server establishes a connection and receives the email:

From this point forward your server has the message and is processing it for delivery to the mailbox of the recipient:
