Setting up Junk Mail Filters

Junk Mail Filters

Overview#

The Junk Mail Filters section helps protect your email accounts from spam, phishing emails, and viruses.

Spam filtering is enabled automatically on all hosted mailboxes.

When an email is received:

• Emails containing viruses are automatically rejected.
• Emails identified as spam are placed in the Junk folder.
• Normal emails are delivered to your Inbox.

You can also create custom rules to block or allow specific senders.

How to Access Junk Mail Filters

1. Log in to your hosting control panel.
2. Click Manage Hosting.
3. Select your hosting package.
4. Click Junk Mail Filters.

You will now see all spam filtering options for your domain.

Inbox Rules

Inbox Rules allow you to automatically organise incoming emails.

For example, you can:

• Move emails from specific senders into folders.
• Automatically sort support emails.
• Organise newsletters into separate folders.

Inbox Rules are managed inside Webmail.

How to Access Inbox Rules#

1. Open Webmail for your mailbox.
2. Click Settings.
3. Click Filters.
4. Select Default.
5. Create your desired rule.

Junk Filter Levels

The Junk Filter Level controls how aggressively spam is filtered.

Current Example#

Available Levels#

Low#

Filters only obvious spam.

Less chance of genuine emails being filtered.

Medium#

Balanced protection for most users.

Recommended for typical business email accounts.

High#

Blocks more spam but may occasionally move genuine emails into the Junk folder.

Useful if you receive large amounts of unwanted email.

Tip: If customers report missing emails, try lowering the filter level and check the Junk folder regularly.

Reject by Sender

Reject by Sender allows you to completely block emails from specific senders, domains, or domain extensions.

Blocked emails will not reach your mailbox.

Add a Domain Rule#

A Domain Rule applies to every mailbox on your domain.

Example#

If you block:

spamdomain.com

all mailboxes on:

autoscale.uk

will reject emails from that domain.

How to Create a Domain Rule#

1. Scroll to Reject by Sender.
2. Locate Add Domain Rule.
3. Select your domain.
4. Enter the sender domain.

Example:

spamdomain.com

1. Click Add Rule.

Block an Entire Country Domain Extension#

You can block all domains ending with a specific extension.

Example:

.ru

This would block emails from domains ending in:

example.ru

company.ru

mail.ru

Add a Mailbox Rule#

A Mailbox Rule only affects one email address.

Example#

Block emails from:

spamdomain.com

for:

info@autoscale.uk

while allowing other mailboxes on the domain to continue receiving them.

Steps#

1. Locate Add Mailbox Rule.
2. Enter the mailbox name.
3. Select your domain.
4. Enter the sender address or domain.
5. Click Add Rule.

Existing Reject Rules

Any blocking rules you create will appear in the Existing Reject by Sender Rules section.

From there you can:

• View rules
• Edit rules
• Delete rules

Allow by Sender

Allow by Sender creates a trusted sender list.

Emails from approved senders will always be accepted, even if they would normally be flagged as spam.

This is useful when important emails are accidentally going to the Junk folder.

Add a Domain Allow Rule#

To trust an entire domain:

1. Scroll to Allow by Sender.
2. Locate Add Domain Rule.
3. Select your domain.
4. Enter the trusted domain.

Example:

amazon.com

1. Click Add Rule.

All emails from Amazon will now bypass spam filtering.

Add a Specific Email Address#

You can allow a single sender.

Example:

trusted@your-friend.com

Steps#

1. Locate Add Mailbox Rule.
2. Enter the mailbox name.
3. Select your domain.
4. Enter the trusted sender email address.
5. Click Add Rule.

Existing Allow Rules

All trusted sender rules appear in the Existing Allow by Sender Rules section.

From there you can:

• View trusted senders
• Edit rules
• Remove rules
