SpamWeeder Premium Filtering

Protection and peace of mind for a small business budget

Affordable Email Security Reliable protection and automatic failover for your email system

SpamWeeder Premium includes anti-spam and virus filtering combined with MX protection and failover for inbound and outbound emails. This solution works with most mail services, is quick to configure, and can be incorporated into complex configurations with multiple mail servers or domains. Use it as a standalone email protection system or combine it with your existing solution for an added layer of security.

SpamWeeder Premium hides your mail server address from the public, making it more difficult for spammers to target it directly.

The filtering engine blocks over 99% of spam, viruses, malware, and other dangerous emails.

MX backup protection is included so that if your mail server malfunctions or loses internet connection, all messages will be stored in the filtering system for up to four days.

Benefits of SpamWeeder Premium Safeguard your network, protect your computers and cell phones, and improve employee productivity with Webservio's email filtering.

Defend Your Business Network

Protect your office network, computers, and employee cell phones from email-based attacks.

Dealing with a virus, malware, ransomware or other security breach can be a nightmare. Many of these threats are delivered by email as an attachment or link. Keeping dangerous emails out of your employees' inboxes helps safeguard your critical IT infrastructure.

Improve Employee Productivity

If your employees have a lot of spam in their inbox, it can severely hamper their productivity.

If your company does not have a filtering system in place, or the current solution is not very effective, you should notice an immediate difference with SpamWeeder Premium. It can significantly reduce the amount of time it takes to sort and read emails without all that junk mail. In addition, you may notice faster download speeds when checking email since your mail server has fewer messages to process.

Simplify Email Management

Unlike most email security options, SpamWeeder Premium does not require an administrator to add individual email addresses.

This flexibile system means new mailboxes and aliases can be quickly configured and will be protected immediately. If the email user needs access to a personal spam quarantine, an administrator can easily add the email address using SpamWeeder's clean, modern interface.

Reduce Infrastructure Costs

SpamWeeder Premium takes the heavy load of message filtering outside of your business network, thereby maximizing your internet resources.

If your on-site firewall and mail server receive a high volume of spam emails, they are also consuming a higher amount of power and internet bandwidth. SpamWeeder Premium is a cloud-based SaaS (Software as a Service) solution. All emails will be scanned before reaching your office network. Implementing this service can improve your internet speed and reduce your power bill!

Safeguard the Good Reputation of Your Business

Outbound filtering can be used to scan messages sent by your employees.

This optional feature will keep employees from accidentally forwarding messages with viruses or other questionable content. It can also help identify email accounts or workstations that may be sending out spam because they are compromised by a virus or hacker. In short, outbound filtering helps protect your business reputation.

How SpamWeeder Premium Works

Uptime Downtime
  1. Implementing SpamWeeder Premium can be completed in as little as one hour. All incoming emails first pass through the filtering system.
  2. If a message is identified as blatant spam, it will be rejected. Other suspicious emails will be added to the spam quarantine. If a message does not trigger the filtering mechanisms and is deemed legitimate, it will be sent on to the mail server.
  3. A daily digest of quarantined messages can be sent to an administrator and/or employees with configured accounts. Users can log into their SpamWeeder Premium account and decide whether to discard the held messages or release them to their inbox.
  4. An administrator can log into the web-based portal to adjust filtering settings, update the white/black lists, view reports and logs, along with other management functions.
  5. Messages sent internally (between employees on the same mail server) do not pass through the filtering gateways.
  6. If outbound filtering is enabled, emails sent from your mail server to outside recipients will also pass through the filtering. Emails with viruses or other suspicious content will be blocked or quarantined.

SpamWeeder Premium Filtering Parameters

A variety of evaluation methods are used to give each email a score based on the likelihood that it could be spam. These measures combined provide a filtering accuracy level close to 100 percent with a near-zero false-positive ratio.

IP Reputation

For every inbound message, SpamWeeder Premium checks the reputation of the sending mail server. A variety of blacklists, SPF checks, and other tests are performed to determine the legitimacy of the sender. Some reputation checks (SPF, DKIM, DMARC) can be enabled or disabled by an administrator. In addition, exceptions can be added to not check particular trusted domains or IPs.


SpamWeeder Premium uses a large number of classifiers to evaluate the message content. If an email includes spammy language, profanity, or other suspcious wording, it will be flagged or quarantined. These content definitions are updated automatically to guard against the latest threats and scams.


The SpamWeeder system can be configured to block specific attachment types that are likely to be malicious. For example, any messages with .exe or .zip files could be automatically quarantined. This parameter could also be used with outbound filtering to prevent potentially sensitive documents from being sent outside the company network.


A restriction can be placed on total email size. This filtering criteria helps prevent emails with large attachments from being delivered to or sent outside your network. Administrators or users can then check the spam quarantine to release messages they know are legitimate.


Domain-wide approved or blocked senders lists can be used to override filtering controls. An administrator can add based on email address, domain, or TLD.

Searches can be further refined based on how the message was classified by the filtering system and the delivery status. Log search results can be exported as a .csv file.
