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.

Hello @Community Alums 

Please check this thread:

Property glide.email.inbound.image_sys_attachment.... - Page 2 - ServiceNow Community

So for example:

• glide.email.inbound.image_sys_attachment.filter.minimum_bytes to 2048 (2MB)
• glide.email.inbound.image_sys_attachment.filter.action to AttachNone
  

This means that any image attachment below this range in the emails will not be attached.

Hi @SatyakiBose 
Can you suggest what to use as the default value if I wanted to totally restrict images from signature? I tried using 1 but images are still being attached.

You need to do some digging and see what the most common size for email signature images.

It will be a time taking activity.

Setting 1 simply means 1KB, which is obviously not enough.

The images in email signatures are more than 1KB for sure.
