Email Links

I have been blocking the url category for web-based email per my company policy, but i am having issues with newsletters that have links.

For example this one I have.

An email comes in to view the upcoming items for sale.

here is the link

Healthy Snacks at Work | Corporate Wellness - fresh2desk

If you look at the link

link.rm0003.net/go/mnQgWuXbk28PhBn7WSw6zw2/

I whitelist link.rm0003.net

But if you put that in the url then this is the real site. Which i cannot allow the users to go to.

ReachMail

Hi markk96,

I did some test. Here is my finding :

link.rm0003.net is categorized as web-based email. But since you have put it in allow list, it is accessible. But this site does change to "go.reachmail.net"

C:\Users\user>nslookup link.rm0003.net

Name: go.reachmail.net <------

Address: 66.251.253.150

Aliases: link.rm0003.net <-----

go.reachmail.net is categorized as computer and info and that is why it is getting allowed.

There are 2 options, for the short term, you can put go.reachmail.net in block list :

go.reachmail.net

*.go.reachmail.net

In the long run, you can request re-categorization for the url category to change it to web-based-email as well. If you are using PAN-DB you can go to following site

Palo Alto Networks URL Filtering - Test A Site

You can go to brightclould site if you are using BC as your URL filtering vendor.

Hope this helps. Thank you.

Yes this is helpful. Going to be curious to see what the next email has for it next month.

Thanks
