Using Cloud anti-spam

Note: Cloud Hosting is no longer available to purchase as of 6th August 2018

Netregistry offers Cloud customers access to an advanced anti-spam solution, which allows users to modify various anti-spam settings from within the Console. You will need to enable Anti-SPAM Services in the console before you can access Spam-Experts Dashboard. Below are instructions on how to access the Cloud anti-spam interface as well as use the various functions in it.

  1. Log into your Account
  2. Manage the domain you want to make changes to
  3. Click Email
  4. Click Manage SpamExpert Settings at the bottom of the page

It is also possible to modify anti-spam options per email address, however the options available per emails address are limited and we recommend users make changes at the domain level instead.

Spam quarantine

Emails which are identified as spam by our Cloud anti-spam filtering system will be redirected into quarantine. These emails will not arrive into the recipients inbox unless manually released by the user from within the quarantine interface. Once in quarantine, users have the option to either release or delete any email which has been marked as spam.

  1. Click on the Spam quarantine icon
    Spam Quaratine icon
  2. Locate the email you wish to release or delete
  3. Click on the release or delete icon

The Cloud anti-spam filtering system will scan the email content of a message based on a combination of advanced statistical filtering technologies, spam fingerprint databases, viruses, phishing, and spyware. Email detected as spam is either temporarily rejected (4xx error code) or permanently rejected (5xx error code) depending on the total score. Email which is permanently rejected at this level is quarantined and available for release (except for viruses). In case a legitimate email would have been permanently blocked, the system will inform the sender that the email did not arrive.

Block attachments

One common method for malicious users to spread viruses is via attachments. Users may configure their account to block emails that contain specific file attachments that may hold malicious content. To add file extensions to the block list, follow the instructions below.

  1. Click on the Attachment restrictions icon
    Attachment Restrictions icon
  2. You will see a Current list of blocked extensions
  3. To Add a new extension type , under Add new extensions
  4. Type in the name of the extension you wish to block in the field provided
  5. Click [Add]
  6. Then Scroll down and click the Save button

Email size limit

To restrict both incoming and outcoming emails which exceed a particular file size, users can navigate to the Email size restriction area and modify their settings.

  1. Click the Email size restriction option on the left
  2. Type in a file size limit (in KB)
  3. Click [Update]

Black and whitelisting

More detailed information about the black and whiltelisting options available within the Cloud anti-spam interface, see our Email blacklists and whitelists support page.

Reporting spam

We are currently working on further integration between our Cloud anti-spam and webmail systems. Once completely integrated, users will be able to report emails as spam or not spam directly within the webmail interface. For the time being, users can manually report specific emails as spam or not spam by exporting their emails from their inbox into .eml files, then uploading the .eml files into the Report spam and Report not spam areas of the Cloud anti-spam system.

There are several tools available online to export emails into .eml files from various email clients such as Thunderbird and Outlook.

Log search

Users may search through the past 28 days of their email logs. This can help users identify if an email was received and whether it was rejected or accepted by the server. The logs also include information such as the email message ID and sending server name, email address and time the email arrived on the server. To access the email logs follow the instructions below.

  1. Click on the Log search icon
    Log Search icon
  2. Select a date range and enter in any other specific details that are relevant to the search you want to perform
  3. Click Start search

Delivery queue

If an inbox is full or there is high load on the server, emails may get held up in the delivery queue prior to arriving in an email accounts inbox. The email queue shows emails which have arrived on our server but are being queued for delivery into a specific email address.

Emails generally pass through the delivery queue very quickly and it is not common to be able to notice any emails held up in this queue.
