Email Aliases

An email alias is an additional address that delivers mail into an existing mailbox. For example, you might have one mailbox for jane@yourdomain.com but also want to receive mail sent to support@yourdomain.com and hello@yourdomain.com in the same inbox. Aliases make this possible without creating separate accounts.

Aliases vs Forwarding

FeatureAliasForward
Delivers to a KapsuleHost mailboxYesNo
Keeps mail on KapsuleHost serversYesOptional
Requires a separate loginNoNo
Can send from the alias addressYes (with client config)No

Use aliases when you want everything in one KapsuleHost mailbox. Use forwarding when you want mail delivered to an external provider.

Adding an Alias in KPanel

  1. Log in to KPanel at kpanel.kapsulehost.com
  2. Go to Mailboxes and open the mailbox you want to add an alias to
  3. Click the Aliases tab
  4. Click Add Alias
  5. Enter the alias address (for example, support@yourdomain.com)
  6. Click Save

The alias is active immediately.

Aliases must be on the same domain as the parent mailbox. To receive mail from a different domain, use email forwarding instead.

Common Use Cases

  • Role addresses: info@, hello@, support@, sales@ all delivered to one inbox (for a team answering one address, see Shared Inboxes for Team Addresses)
  • Name variations: firstname@ and firstname.lastname@ pointing to the same account
  • Catch-all addresses: Receive mail sent to any address at your domain

Setting Up a Catch-All

A catch-all address receives any email sent to your domain that does not match an existing mailbox or alias. This prevents legitimate messages from bouncing.

  1. Go to Mailboxes in KPanel
  2. Click Catch-All Settings for your domain
  3. Select the mailbox to receive unmatched email
  4. Click Save

Catch-all addresses tend to receive a high volume of spam, since spammers often guess random addresses at known domains. Monitor the inbox regularly or use an alias for specific addresses instead.

Removing an Alias

  1. Open the mailbox in KPanel
  2. Go to the Aliases tab
  3. Click Delete next to the alias you want to remove
