"email-headers" and "smtp-email-headers" context in customer application definition

L1 Bithead

Hello,

Is there any difference between "email-headers" and "smtp-email-headers" context in the customer application definition?

I didn't find description of the "smtp-email-headers" context in "Custom Application IDs and Signatures" guide.

Maybe "email-headers" can be used for any email protocol and "smtp-email-headers" only for SMTP?

Thanks

The last I saw there were options for HTTP headers but I didn't see for email headers but you can double check it. See the link below and search for ''Pattern match''' with smtp:

Hello Nikolay.

I wrote that I didn't find description of the "smtp-email-headers" context in Custom Application IDs and Signatures  guide. But this context is present in the list of available context options for Customer App in the real device software (for example PA-820, at least for s/w 9.1.x and later). See attached screenshot.

The "email-headers" context description can be found using Search Box under Table of Contents in the document mentioned in your answer. Link to search result is
https://docs.paloaltonetworks.com/pan-os/u-v/custom-app-id-and-threat-signatures/custom-application-...

As I didn't find "smtp-email-headers" description I hoped someone explains the difference between these 2 contexts.
