Whitelist for encrypted attachments

traxxed
Hi,

I'm using the UTM9 soft appliance as an SMTP proxy, but I'm having trouble configuring this w/ regards to incoming Emails with encrypted attachments (like password-protected zip-files). Basically, what I want to do is:

-default action for encrypted attachments should be quarantine
-define a whitelist for sender addresses allowed to send plain text Emails with encrypted attachments

Problem is, even though I defined a whitelist and skipped the "Email Encryption" check for it, emails w/ encrypted attachments coming from the senders I whitelisted are still getting quarantined. The only way I found so far to get those Emails through is to skip the "Antivirus checking" check as well, but that's not what I want. Antivirus checking should always occur, but unscannable attachments should be ignored for senders I whitelisted.

Is it possible to do this?

Thanks

    Hi, traxxed, and welcome to the User BB!

    The Encryption exception relates to encrypted full emails, not encrypted attachments.

    On the 'Anti-Virus' tab, you can select 'Quarantine unscannable and encrypted content', but there's no way to skip that selectively without skipping anti-virus checking altogether.

    This is an interesting idea though, so you might want to submit a Feature Request.

    Cheers - Bob

    Hi Bob,

    Thanks for your answer. That's what I was afraid of :-)

    I'll go ahead and log a feature request then.

    Thanks again
