mailx command

Hi,

I am seeing that this command is sending mail even when the nawk command in untrue ( does not have any output ). I only want it to send mail, where it goes above the threshold, and has some output.



Code:
nawk -F'(MOD dn="uid=)|(DEL dn="uid=)|[,]' '/(MOD dn="uid=)|(DEL dn="uid=)/ {u[$2]++}END{for(i in u) if(u[i]>thr) print "user",i,"has crossed ["u[i]"] the thresold limit ",thr}' thr=100 access | mailx -s 'Thresold Email' TO_EMAIL_ID

Can someone help me on this?

Thanks.
