???? how would you receive any mail from Internet?

What's the point of accepting msg for a user Imail doesn't have?
>Or will it still relay mail to users even if the mail originates

"relay"
means
"accept mail from some server and send to some other (non-local) server"
"open relay" means do the above for sending server.
"closed relay" means don't relay except under certains conditions.
accepting mail for a local "@recipientdomain" is not considered "relay".
>Well. luckily mine are pretty consistently between 800 KB and 1 MB. :)
That's 40 kb/hour, so if you had some tool that could tell the file
size on the hours and compute the increment in log size since the
last hour, then you could set a threshold of 80 kb (double) that
triggered an email to you saying "the last hour's log grew by 80 kb,
better take a look"
even better, since you don't care about all the POP3 stuff mixed in
there, being spammed is just SMPTD lines, not SMTP lines, at every
hour :59, you could count just the SMTPD lines for the cureent hour
(last :59 minutes) and pull somebody's chain if you had too many SMTPD lines.
Same approach for lines containing "ERR" or "invalid user"
one of these days...
