SolarWinds Spam Experts is a leader in the e-mail security market. In order to provide the most secure services to the customers, SiteGround has integrated the SolarWinds Spam Experts solutions on our shared and cloud servers.

In this way, the incoming and outgoing e-mail messages are filtered and the delivery of spam is prevented.

One of the great benefits of the SolarWinds Spam Experts solution is that the system cluster can be taught. All the suspicious e-mails are stored in a Spam Quarantine queue and the clients can mark chosen messages as legitimate.

The SolarWinds Spam Experts control panel can be opened from Site Tools>Email>Spam Protection>Login.

Once the page loads, the domains associated with the account are listed.

Click on the Login link next to the chosen domain to open the The SolarWinds Spam Experts control panel.


With this tool, you can search the logs for a specific incoming e-mail message based on different criteria like the name, the host and the IP of the sender, the name of the recipient, a chosen data range and more. The deprecated log search page, which includes a “latest results” method, may still be used.

Spam Quarantine

In the Spam quarantine tool, all the suspicious messages associated with the current domain are stored. It contains the messages that are permanently blocked by the anti-spam system.  The messages can be deleted or released. If they are released they will appear in the recipient’s mailbox. The cluster will be trained automatically which messages are legitimate and will release similar ones in the future.

The suspicious messages that are temporary rejected are not included in the quarantine system. Their delivery will be automatically retried by the sending servers.

Delivery queue – incoming

Here you can find a list with the messages in the delivery queue associated with the corresponding e-mail accounts. You can see the reason for the messages to stay in the queue and can try to manually force their delivery.

Domain aliases

Configuring a domain alias means that mail received for recipients at the alias domain will be treated in the same way as if they had arrived at the primary domain. For example, if you have the domain, and an alias, then mail to ​ will use the settings for ​, spam will be placed in the ​ quarantine, and log entries will be available under the ​ address.

Filter settings

Here you can control the activation of the quarantine system.
