My favorite is this: May 18 01:47:59 puck sendmail[26336]: NOQUEUE: Null connection from hub.FreeBSD.ORG [204.216.27.18] May 18 09:02:21 puck sendmail[31482]: NOQUEUE: Null connection from hub.FreeBSD.ORG [204.216.27.18] I get these periodically. The only way you get these is if someone connects to your smtp port and then does a "QUIT" without doing anything else. - Jared On Mon, May 18, 1998 at 10:55:38AM -0500, J.A.
