Our new spam system is integrated with 3rd party global spam fighters. (Mail Filters). This system does learn, but you may wish to report any spam that gets through to your mailbox by emailing it directly to [firstname.lastname@example.org|mailto:email@example.com. From there it will be scanned and included in the worldwide spam database for future filtering.
If you receive any emails marked as spam that are in fact real emails, you can report those in the same way to firstname.lastname@example.org.
Please be sure to attach the email, rather than simply forwarding it, as this will include the relevant header information as well.
