I am trying to configure a SF300 to filter all outbound mail on a public VLAN in a hotel complex. I can find no documentation for this configuration.

How can I filter all outbound mail on a "guest VLAN" so it does not flood the outbound and blacklist the public IP? Keep in mind there is no mail server involved, only mail clients for example Outlook, Thunderbird, Outlook Express, etc.. Since these are guest PC's (hotel guests) there is no access to configure the mail clients.

Do I route ALL network traffic for that VLAN through the SF300?
Doesn't the SF300 only handle mail traffic?

If I have a laptop come into a network with a spambot, how do I keep it from shutting down my IP?

Hi ryan,

The Barracuda spam and virus firewall only handles SMTP traffic.

You need to create Policy Based Routing via your outbound firewall to funnel all destined SMTP traffic thru the Barracudas Interface.. this way only the BSF can send SMTP out and all other network points will be blocked from sending outbound emails.
