Restrict images from email signature in inbound email

[Community Alums]

I would like to seek guidance or any idea on how to avoid attaching images from email signatures that comes from inbound email actions. I found one article from ServiceNow that says we have to update 2 system property records but I'm having some confusion about what should I put on the system property named "glide.email.inbound.image_sys_attachment.filter.minimum_bytes". Based on the article, when the value is set to 0, it disables the filter. So how can I enable it? Should I put a higher number?

Thank you.

But setting the default value means that file size below the default value will still be attached to the ticket, is my understanding correct?

You're right that email signature images are typically larger than 1KB, but just to clarify—the setting "1" doesn’t mean 1KB; it actually means 1 byte. So if you wanted to prevent adding image that's up to 1MB, you'd need to set the value to 1,000,000.
