Problem with Encrypting Content Filter

[Kurtis Franklin]

Hello,

I have two C160s and I'm having trouble getting certain content filter rules to encrypt. Essentially, I've done the following:

1. Created a rule that examines the subject line if ENCRYPTED is at the beginning, it encrypts the email and delivers

2. Created either a second condition or a second rule (both have the same result) that looks for the [SEND SECURE] subject at the beginning that the Outlook plugin prepends, encrypts and delivers the email.

If the second rule/condition is applied and active on the default policy, it encrypts ALL message EXCEPT those that have the [SEND SECURE] at the beginning of the subject line. Am I doing something wrong? Is there another way to capture the [SEND SECURE] prepend the Outlook plugin creates or to change it in some way?

Hello Kurtis,

It is difficult to say what is wrong without seeing your filters and related logs. However, I am providing link to our knowledge base article below for your reference.

Hello Kurtis,

your problem lies in the fact that the filter condition is actually a regular expression. In your case, putting something in square barkets means the condition will catch on any single character within the expression. To prevent that to happen, use a backslash in front of the barakets:

\[SEND SECURE\]

Note that after submitting, you will see that the line will change to  \\[SEND SECURE\\] , that's normal and intended.

Hope that helps,

BTW, you might find similar topics about this in the community.

I guess that's just further proof that I should have spent some time learning regular expressions. Thank you for taking the time to look at my problem. I'll read through that documentation again. I assume there is some documentation for the outlook plugin as well, so I'll look for that. Thanks again.

Kurtis,

The administrators guide for the plugin can be located here.

Thanks Christopher,

Exactly what I was looking for before I deploy this to the rest of my users. Especially like the ability to have the plugin use a header instead of using the subject line. That should make some people here very happy. Thanks again to everyone for your help.
