What type of "NOOP responses", from your internal SMTP host? It will respond, but ISA will not check for buffer overflow tries. -----Original Message----- From: David Dellanno [mailto:david@xxxxxxxxxx] Sent: sábado, 4 de agosto de 2001 12:00 To: [ISAserver.org Discussion List] Subject: [isalist] RE: SMTP Events http://www.ISAserver.org Hi Hugo, Interesting, I disabled NOOP under SMTP Commands and still receive NOOP responses. -----Original Message----- From: Hugo Caye [mailto:Hugo@xxxxxxxxxxxxx] Sent: Friday, August 03, 2001 10:38 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: SMTP Events http://www.ISAserver.org ISA Mgr Utility Your_Server Extensions Application Filters SMTP Filter Properties SMTP Commands NOOP Just edit it and change the maximum length to.... let say, 64. -----Original Message----- From: Thor@xxxxxxxxxxxxxxx [mailto:Thor@xxxxxxxxxxxxxxx] Sent: sexta-feira, 3 de agosto de 2001 11:10 To: [ISAserver.org Discussion List] Subject: [isalist] SMTP Events http://www.ISAserver.org Greets: I continually get SmtpEvt EventID: 17240 in my ISA Server's Application log described as "The SMTP command exceeded its allowed length" with data of "NOOP" However, there is no information as to the offending IP, or anything else for that matter. Nothing is in any of the logs to correlate to. Is there any way to get more information as to what this is and who is causing it? In general, I would like to at least know the offending IP... --------------------------------- Attonbitus Deus Thor@xxxxxxxxxxxxxxx ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: Hugo@xxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: david@xxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: Hugo@xxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
