A forwarder sends messages arriving at one hosted address to another address.
Applies to: SiteWorx hosting email
Create the forwarder
- Sign in to SiteWorx.
- Open Hosting Features > Email > Aliases.
- Select the option to add an alias or forwarder.
- Enter the source address and the destination address exactly.
- Save the rule.
- Send a test from an unrelated external address and confirm the destination receives it.
Important delivery considerations
- Forwarded mail can fail external anti-spoofing checks even when the original message was legitimate.
- For important mail, using a mailbox and collecting it with IMAP is generally more reliable than forwarding everything to another provider.
- Avoid forwarding loops and chains through several providers.
- A forwarder does not create a mailbox unless a mailbox is created separately.
Common problems
| Symptom | Likely cause | What to do |
|---|---|---|
| The source address rejects mail. | The alias was not saved, conflicts with another object or the domain MX is elsewhere. | Check aliases, mailboxes, groups and public MX records. |
| Some forwarded messages never arrive. | The destination provider rejected the forwarded message based on authentication or reputation. | Check the destination spam/quarantine and use a normal IMAP mailbox for critical delivery. |
