Encrypted PDFs

I've seen the posts about how to allow them all or deny them all.
I've also seen how to allow them through one-by-one after the fact.


When can we see Zimbra add a bit better UI on how to whitelist particular senders with regards to encrypted PDFs? Things like paystubs are sent as encrypted PDFs. I've seen other systems send legitimate e-mail that's an encrypted PDF. Obviously, you can't just whitelist all encrypted PDFs because some are malware.

Back to manually pushing through ones that have already been blocked...

https://bugzilla.zimbra.com/ Is where you should place a feature request.

I have not seen any feature requests for it so not sure you will see,the feature anytime soon :(

I think what you want is this virus_name_to_spam_score_maps ... This would allow you to score this in SA and provide that flexibility.

Anything matching would be sent on to SA where you could look at X-Amavis-AV-Status to see if that was an encrypted pdf... then create a meta rule to allow your senders through... else score it to non deliverable.
