I am getting a lot of Event ID 17240 in my application log.

These events indicate "The SMTP command exceeded its allowed length"

The data is "NOOP"

This is a result of the SMTP filter (under Extensions > Application Filters). This filter is configured to allow NOOP commands with a maximum length of 6 bytes by default.

Apparently I am receiving NOOP commands longer than 6 bytes.

Should I just guess how long a NOOP command I should allow? I thought the NOOP command was pretty much just that -- you say NOOP and the SMTP server says OK. Why would I be getting long NOOP's?

Hi Ben,

From what I understand, there's really no purpose for NOOP. You can increase the length of the command in the ISA Management console, or you can completely remove the filter for it.
