Protection against spam, viruses and phishing attacks
The software solution for anti-spam and virus protection
Anti-spam with REDDOXX
Every day, companies receive thousands of unwanted emails – including dangerous phishing scams, malware and annoying advertising. REDDOXX Spamfinder reliably filters out these threats at the email gateway before they put a strain on your systems or endanger your employees.
Cyber criminals use deceptively genuine emails to steal access data and sensitive information. Phishing is now the most common method used in successful attacks.
The majority of global email traffic consists of spam. Without effective protection, not only performance suffers, but also the overview in the mailboxes.
Ransomware & co. often reach companies via email. Just one click on an infected attachment can have far-reaching consequences – from data loss to operational downtime.
Even well-trained teams occasionally overlook well-crafted fraud attempts. A technical filter significantly reduces this risk – automatically and in the background.
Protection against data loss and unauthorized access is required by law. An effective spam filter contributes to compliance with the GDPR and internal guidelines.
Fewer support requests, fewer malware emergencies, less memory load: a reliable spam filter saves resources and ensures trouble-free mail operations.

How REDDOXX Spamfinder works
The REDDOXX Spamfinder is integrated into your existing infrastructure as an appliance and filters all incoming emails at the gateway before they reach your systems or mailboxes. Set-up is straightforward and operation is low-maintenance and runs in the background.
1. installation and setup
Spamfinder is integrated into your existing IT infrastructure as a virtual appliance. It is installed on your preferred virtualization platform – e.g. VMware, Hyper-V, XEN, KVM, Proxmox or other hypervisors.
The appliance acts as an SMTP gateway between the mail server and the Internet, so that incoming emails first pass through the filter system before they are delivered.
The integration is independent of the mail server used: Whether Microsoft 365, Exchange, Postfix, Zimbra or others – communication takes place via standardized channels. Hybrid or distributed structures can also be easily connected.
2. activation of the filter mechanisms and rule definition
After technical integration, you configure the protective functions. The centerpiece is the self-learning Fuzzy filter that matches the content of incoming mails with known spam patterns, supported by a continuous Honeypot procedure and reputation data.
The Spamfinder also checks incoming emails for SPF, DKIM and DMARC.
The system can be flexibly adapted to company requirements via individually adjustable threshold values, whitelists and blacklists.
3. quarantine management with user access
Emails that are classified as spam do not end up in the inbox, but in a centrally managed Quarantine. Depending on the configuration, authorized users can decide for themselves whether a message should be delivered.
A web-based quarantine portal, Outlook integration and automated daily reports allow users to keep track of blocked messages without burdening IT. Optionally, release processes can be defined or quarantine-specific retention periods can be set.
4. low-maintenance operation & continuous updating
REDDOXX Spamfinder updates its signatures, patterns and reputation data fully automatically and at short intervals. This means that protection remains up to date even in the event of new attack patterns, without manual maintenance or recurring administration tasks.
The system runs in the background in a resource-saving and stable manner, can be administered at any time via the web interface and offers meaningful statistics on filter performance.
In short: once set up, Spamfinder runs reliably and almost maintenance-free.
The REDDOXX Appliance is a virtual machine and can be installed under almost any hypervisor. VMware, Hyper-V, Citrix XEN, KVM, Proxmox, Nutanix AHV or Virtual Box are supported, among others.
Yes, REDDOXX Spamfinder works server-independently and can be easily integrated into almost any environment – whether Microsoft 365, Exchange, Zimbra, Postfix or others. The connection is made via standard protocols such as SMTP and POP3.
Yes, every user can view their quarantine via a web portal or daily email reports and release or block emails. This reduces queries to IT and increases acceptance.
The Spamfinder checks every incoming email for SPF, DKIM and DMARC. In addition, REDDOXX’s own fuzzy filter is used, which compares content with known spam patterns. This means that even sophisticated attacks are reliably detected.
The integrated spoofing filter also checks whether internal addresses come from external networks and rejects them if there are no whitelist entries for them (e.g. for online stores).
All filter rules, virus signatures, honeypot data and blacklists are updated automatically – several times a day. This means that your protection is always up to date, even in the event of new attack patterns.
Yes, because spam and malware are already filtered out at the gateway, the volume of emails that the mail server has to process is significantly reduced. This saves resources and improves performance.
