Did you notice the comments at the top of default master.cf file? They
explain the syntax:
> # service type private unpriv chroot wakeup maxproc command + args
If you compare this to the line in question:
> smtp inet n - n - - smtpd
"service" is "smtp"
"type" is "inet"
"private" is "n"
"unpriv" is "-" ("-" means use default value)
"chroot" is "n"
"wakeup" is "-" (default)
"maxproc" is "-" (default)
"command + args" is "smtpd"
So answer to your question is: "smtpd" is the name of the executable that is
run to provide this service. Both services, on port 25 and 587, are provided
by two instances of the same executable, therefore "smtp" in both cases.
After "smtpd" there can be arguments used to call this executable - these
arguments are used to make both services operate differently.
