WildDuck is a simple mail server solution and is often accompanied by the WildDuck Webmail service. While you can create email addresses with any domain via both the WildDuck’s API and the Webmail GUI, when it comes to aliases and the ease of use of the user interface, by default you’re only limited to the one you’ve initially configured.

To add further domains to choose from when creating alias addresses, edit the wildduck-webmail.toml file (it is located in /etc/wildduck/) and add your additional domains in the domains=[] array like so:

[service]
...
# allowed domains for new addresses
domains=["oviliz.com","seconddomain.com"]

Restart the webmail service with systemctl restart wildduck-webmail and you’re good to go.

Now if you want to also create a separate DKIM key and DNS record, follow this short guide.
