Quarantine incoming .zip files

In an effort to deal with recent virus issues I have created a mail rule on the server to block .zip attachments. Currently the rule quarantines both incoming and outgoing files. I want to allow outgoing .zip attachments but quarantine incoming .zip attachments. Is this possible?

Subject: Quarantine incoming .zip files

I just had to tackle this today.

I solved this by creating a mail rule that quarantines both .exe’s and .zip’s, but excludes our Domain. Please see the following:

When Internet Domain Does not Contain Olympic

AND Attachment name Contains .exe

OR Attachment name Contains .zip

Action:

Move to quarantine.nsf

Hope this helps you out.

Subject: Rule oddity worth mentioning…

For some reason the aforementioned rule would not process the:

OR Attachment name Contains .zip

I had to remove it from the original rule and create another seperate rule, just like the first, for the .zip’s.

This corrected the issue, but I’m still looking into why the original rule syntax did not work as expected.

Subject: AND/OR Logic problem…

If you could write the rule this way it would work.When Internet Domain Does not Contain Olympic

AND (Attachment name Contains .exe

OR Attachment name Contains .zip)
