I do exactly that, turn on the email from = email to filter, as if a user sends a note to themselves then the path of the message is

Client --> Email Server (Exchange) --> back to my mailbox.

So it will never see the spamfilter server.

AndrewD is correct, legitimate users who send emails to themselves will usually do so without having SpamFilter stopping those emails, as in most implementations of SpamFilter, the end users are using your SMTP server, not SpamFilter, in their "outgoing SMTP server" configuration in their email clients.

If that is not the case (meaning your users are using SpamFilter to relay their emails rather than your SMTP server), in this case you most likely are having your users authenticate with SpamFilter (via SMTP AUTH) before sending the emails, in which case they will be whitelisted and will thus bypass the filter.

This said, usually a better method to stop these kind of emails is by implementing SPF in your DNS (see openspf.org), and enabling the SPF filter in SpamFilter. SPF allows you to control, via a special record in your DNS (the SPF TXT record), who is authorized to send emails on behalf of your domain (@e-advice.dk). Only the servers you authorize will be able to send emails from @e-advice.dk. SpamFilter will reject any such senders unless they are allowed by your SPF record.
