Aliases, groups & routing
Control where mail goes: extra addresses for a person, shared team addresses, forwarding, and a catch-all for anything unmatched.
Aliases
An alias is an extra address that delivers into an existing mailbox — no seat used. Add them on a mailbox (Mailboxes → (mailbox) → Aliases). Example: sales@ and hello@ both land in one person's inbox.
Distribution groups
A group address fans one email out to several people. Mail to team@yourcompany.com is delivered to every member. Manage members under Groups. Good for departments and announcements.
Shared mailboxes
A shared mailbox (e.g. support@) that several people can access — useful for a team inbox where anyone can reply. Add members under Shared mailboxes.
Forwarding
Send a mailbox's incoming mail to another address. Choose whether to keep a copy in the original mailbox as well. Set it per mailbox, or use routing rules for domain-wide forwarding.
Catch-all
A catch-all delivers mail sent to any unmatched address on your domain (e.g. a typo like jon@ instead of john@) to one mailbox, so nothing is lost. Set it under Routing. Use sparingly — it can attract spam.
Alias vs group vs sharedAlias = one person, extra address. Group = copy to many people. Shared mailbox = one inbox several people open.
Troubleshooting
| Problem | Cause | Fix |
|---|---|---|
| Can't create a mailbox with a name | An alias or group already uses that address. | Remove the alias/group first, or pick a different address. |
| Group mail isn't reaching everyone | A member address is wrong or inactive. | Check the member list; remove bad addresses. |
| Forwarding stopped keeping a copy | “Keep a copy” is off. | Edit the forwarding rule and enable keep-copy. |
| Catch-all flooded with spam | Catch-all accepts every address. | Turn it off and use explicit aliases instead. |
