Proxmox Mail Gateway : How to add “EXTERNAL” warning on email subject

Posted by

After adding the subject information to the log, I want to add an “EXTERNAL” warning on the email subject. So, users know if the email comes from external.

Below is what I did:

– Go to PMG Dashboard -> Mail Filter -> Action Objects
– Click Add and select Header Attribute
– Add information to the Name and Comment
– Fill subject in the Field
– Fill [EXTERNAL] __SUBJECT__ in the Value

[EXTERNAL] __SUBJECT__

– Go to PMG Dashboard -> Mail Filter
– Click Add Rules
– Add information to the Name
– Fill 99 in the Priority
– Select in on Direction section
– Tick on the Active section

– Select Action Objects that has been created from Available Objects -> Action

Now, you can see additional line “EXTERNAL” on email subject when received email from internet

If you need PMG Support and Subscription, please feel free to contact my Company: https://www.excellent.co.id/kontak/

Good Luck 🙂
