Every email account in hMailServer must belong to a domain. The domains specified in hMailServer can be local network domains or global internet domains such as hMailServer.com.
If you set up a domain named example.com, and an alias named example.net, your server will accept email for both email@example.com and firstname.lastname@example.org. Your users will be able to log on as both email@example.com and firstname.lastname@example.org as well.

These two fields specify the domain signature to be used
DKIM, Domain Keys Identified Mail, is a method to sign the content of messages. The recipient can verify that the message is sent from a server authenticated to send from the sender's domain, and that the message content has not been modified in transit.
Before hMailServer delivers a message to another server, it will look at the sender address of the message. If the sender address matches a local domain, the DKIM signing options from that domain will be used. If DKIM signing has been enabled, the message will be signed.
Whether or not the original sender has used SMTP authentication when delivering the message to hMailServer has no effect on the DKIM signing process.
hMailServer only DKIM-signs email messages delivered to other servers. If a user on a hMailServer installation sends a message to another user on the same server, the message will not be signed.
It is possible to specify an email address that receives all emails being sent to non-existent addresses on your domain. For example, you may have
email@example.com as existing accounts. But there's a risk that someone might misspell an email address, writing
firstname.lastname@example.org instead of
The solution is to specify an account - either a previously existing one, or one created for the purpose - to be the catch-all account. All email sent to non-existent addresses on the domain will then be delivered to the catch-all account.
email@example.com catch-all address
