Email Aliases, Identities, Plus & Subdomain Addressing
TL;DR — One EasyCloudify mailbox can receive on unlimited addresses thanks to aliases, plus addressing, and subdomain addressing. Identities let you reply from any of those addresses. Wildcards let one mailbox send for the whole domain.
EasyCloudify mailboxes are designed so a single mailbox can power dozens of public-facing addresses (info@, sales@, support@, hello@…) without paying for extra accounts and without juggling multiple logins.
This guide explains four overlapping features. You can use any combination of them.
| Feature | What it does | Set up at |
|---|---|---|
| Aliases | Receive mail for additional addresses on the same domain | /cloudpanel/mailboxes → Aliases |
| Identities | Send mail as additional addresses | /cloudpanel/mailboxes → Identities |
| Plus addressing | Auto-generate [email protected] addresses on the fly | Nothing — works automatically |
| Subdomain addressing | Receive at [email protected] | Nothing — works automatically |
| Wildcard sending | Send as any address on a domain you own | Set on the mailbox |
Aliases
An alias is an extra incoming address that delivers to an existing mailbox.
Example: Your mailbox is [email protected]. You add the alias [email protected] — mail sent to [email protected] is delivered to your [email protected] inbox.
Create an Alias
- Go to
/cloudpanel/mailboxesand select your domain - Open the Aliases tab
- Click Create Alias
- Fill in:
- Local part — the alias prefix (e.g.
info) - Destinations — one or more mailbox addresses to deliver to
- Local part — the alias prefix (e.g.
- Click Save
Multi-Destination Aliases
An alias can deliver to multiple mailboxes at once. For example, [email protected] could fan out to [email protected] and [email protected]. List all destinations separated by a comma in the form.
Replying From an Alias
To reply as the alias (so recipients see info@ instead of me@), add it as an identity — see the next section.
Identities
An identity is an additional outgoing From address attached to your mailbox. Identities let you send mail as an alias, an alternative name, or even from another domain you own.
Create an Identity
- In
/cloudpanel/mailboxes, open the Identities tab - Click Create Identity
- Fill in:
- Local part — e.g.
infofor[email protected] - Name — display name shown on outgoing messages
- Password (optional) — set one if you want this identity to authenticate via SMTP on its own (rare; usually you authenticate as the parent mailbox)
- Local part — e.g.
- Click Save
Use an Identity in Your Email Client
- Webmail — pick the identity from the From dropdown when composing
- Thunderbird — Account Settings → Manage Identities → Add
- Apple Mail — Mail → Settings → Accounts → your account → Email Address → Edit Email Addresses
- Outlook — File → Account Settings → your account → Change → More Settings → Reply email address
Once added, your client shows a From-address picker on every new message.
Aliases vs. Identities
- Alias = receive on an extra address
- Identity = send from an extra address
- Most people want both for the same address — e.g.
info@should receive and be a valid From address. Set up both for the same local part.
Plus Addressing
Plus addressing lets you generate unlimited single-use addresses on the fly without any setup. Anything between a + and the @ in your address is ignored for routing but kept visible.
Examples — all deliver to [email protected]:
Why Use It
- Track who shared your address. Sign up for service X with
you+serviceX@…— if spam later arrives at that exact address, you know X leaked it. - Filter automatically. Most clients can filter messages whose To address contains
+newsletterinto a Newsletters folder. - Auto-create folders. Plus-addressed messages can be automatically dropped into a matching IMAP folder (see Email Folders & Auto-Deletion).
Notes
- Some signup forms reject
+in the local part. Use a regular alias instead in that case. - Plus addressing is case-insensitive —
you+News@andyou+news@are equivalent.
Subdomain Addressing
Mail addressed to [email protected] is delivered to [email protected], regardless of what anything is.
Examples — all deliver to [email protected]:
Why Use It
- Hand out per-context addresses without creating per-context aliases
- Easier filtering and tracking than plus addressing for senders that strip
+ - Useful for testing — set up a temporary
[email protected]address with zero configuration
Notes
- Subdomain addressing is enabled automatically. No DNS changes are needed.
- Sending as a subdomain address requires creating a matching identity — sending defaults to your real address otherwise.
Wildcard Sending
A mailbox can be granted wildcard sending permission so it is allowed to send mail as any address on a domain you own. Useful for transactional senders or for a small team that needs to send from many addresses without managing many identities.
Enable Wildcard Sending
- Open the mailbox in
/cloudpanel/mailboxes - Choose Edit Mailbox
- Toggle May Send From Any Address (Wildcard)
- Click Save
⚠️ Use sparingly. Wildcard permission means anyone with the mailbox password can send as any address on your domain — including
ceo@,accounts@, etc. Only enable on mailboxes used by trusted automated processes or experienced users.
Catch-All Address
A catch-all forwards mail addressed to any unrecognised local part on a domain to a chosen destination. Useful for capturing typos and for personal domains where you want everything to land in one inbox.
Set Up a Catch-All
- In
/cloudpanel/mailboxes, open the Forwardings tab - Click Create Forwarding
- For Local part enter
*(asterisk) - For Destination enter the mailbox to receive the catch-all mail
- Click Save
⚠️ A catch-all increases spam: every made-up address on your domain becomes a valid target. Set up aliases for known addresses first and only use catch-all when you genuinely want everything.
