This works for me:

log stream --predicate  '(process == "smtpd") || (process == "smtp")' --info

###Explanation: --predicate is used to filter the log. In this case it looks for the process "smtpd" or "smtp"

--info shows all messages down to info level, which is good for most purposes.

Hope this helps!
