What happens when someone emails salez@yourdomain.com — with a typo — or an address you never created? By default, that mail needs somewhere to go, and the Default Address (or catch-all) setting decides. Getting this right can save lost mail or spare you a flood of spam. Here’s how it works.
What the default address does
The default address catches any mail sent to an address on your domain that doesn’t have its own mailbox or forwarder. You have three main choices for what to do with it: forward it to a real mailbox, discard it silently, or discard it with an error sent back to the sender.
Setting it up
- In cPanel, open Default Address under the Email section.
- Select your domain.
- Choose an action: forward to an address, or discard.
- Save.
The case for forwarding (catch-all)
Forwarding everything to a real mailbox means you never miss a message due to a typo, and you catch mail sent to addresses you forgot you’d advertised. This is genuinely useful for a small business — a customer who mistypes your address still reaches you.
The big downside of catch-all
Here’s the catch: a forwarding catch-all is a magnet for spam. Spammers send to random addresses at domains — info@, admin@, john@, thousands of guesses — and a catch-all delivers all of it to your mailbox. On an established domain, this can be an overwhelming volume of junk. For that reason, most people are better off not using a forwarding catch-all.
The recommended setting: discard
For most domains, we suggest setting the default address to discard. Legitimate senders using a correct address still reach their intended mailbox; only mail to non-existent addresses (which is mostly spam and typos) gets dropped. Choosing “discard with an error” politely tells a genuine sender their address was wrong, so they can correct it.
A middle-ground approach
If you’re worried about missing typo’d mail but don’t want the spam flood, create specific forwarders for the addresses people commonly get wrong — variations of your real addresses — rather than catching absolutely everything. This gives you the safety net where it matters without opening the floodgates.
Review it periodically
If you’ve had a forwarding catch-all running and your inbox is drowning in spam to made-up addresses, switching the default to discard often brings dramatic, instant relief. If you’re wrestling with email spam, this setting is well worth checking — and we’re happy to help you find the right balance.
