I set up a sonicwall to block internet to users on a certain switch port. Works well, but now they want to access email, while still blocking the internet. I can't figure out a way to do this using Sonicwall without buying the Content Filtering Service. They just use pop3, so I'm not aware of any sort of onsite pop3 bypass I could set up internally?

1Create an outbound rule for POP. What's Content Filtering got to do with it? I don't understand the dilemma. – joeqwerty Sep 17 '15 at 17:11

1Sorry, momentary brain-dead day apparently. Not sure why this escaped my understanding so much. – Douglas Lawson Sep 26 '15 at 17:55

You don't need the Content Filter Services (which, by the way, serves a different scope: it selectively block some web categories, all running on the standard HTTP port).
You simply need to configure a LAN to WAN rules enabling DNS and POP3 for the selected IP/users, while blocking all other traffic.

Perfect, someone else had this exact same suggestions. I'll need to configure SMTP too I'm assuming? – Douglas Lawson Sep 18 '15 at 18:25

It really depends on what you need. If you want to enable emailing _and_ your mail server is external to your network, you likely need to enable POP3, POP3S, SMTP, SMTPS, IMAP, IMAPS and DNS. – shodanshok Sep 19 '15 at 16:41
