MailEnable Standard and Barracuda SPAM filter

[cclarke]

When email is sent to a domains MX servers that uses our Barracuda SPAM filtering device, the email will go through the Barracuda SPAM filters and then make it to the MailEnable server. However, some spammers are sending directly to the MailEnable server and bypassing the Barracuda SPAM filters.

Is it possible with MailEnable Standard to allow incoming email to come only from 1 IP (our Barracuda SPAM filter) and allow all users who authenticate to send email out?

Just to clarify this:

We would need to upgrade to Enterprise Edition $699 and configure as per the documentation on a post office level so domains not using inbound filtering will work as normal.

The main question is from the docs where it says:

"These settings for MailEnable will force all inbound connections to authenticate even if they are simply sending to the server. The setting will force all senders to your server to authenticate. Do not forget to add the IP of the remote mail filter/proxy server(s) as an authenticated sender by adding the IP to the relay list."

If we "add the IP of the remote mail filter/proxy server(s) as an authenticated sender by adding the IP to the relay list.", the spam filtering device will not need to authenticate to send the emails to the mail server because it is listed as an authenticated sender and able to relay?

The reason I ask this is that the barracuda spam filter does not have a way to authenticate when forwarding email to the destination server.

Yes, that is correct.
