Attachment icons / images of Signatures continue to display even after setting system property 'glide.email.inbound.image_sys_attachment.filter.action'

 

Problem

---

When processing inbound emails which has images such as attachment icons / logos / email signature, platform creates duplicate records in sys_attachment table for the target table record even if system property glide.email.inbound.image_sys_attachment.filter.action value is set as AttachNone.

 

Symptoms

---

1. Duplicate image attachments in Manage Attachments section at the top of table record in form view which keep on increasing with forth coming reply emails.
2. Same duplicate images keep on appearing on the Activity Notes in addition to Email updates.

Resolution

---

Using system property glide.email.inbound.image_sys_attachment.filter.action alone does not work. To filter images from emails and reduce duplicate image attachments to target records, configure both of below mentioned system properties:

1. glide.email.inbound.image_sys_attachment.filter.minimum_bytes
2. glide.email.inbound.image_sys_attachment.filter.action
