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.
The name of the domain. To be considered valid, a domain name must include a dot. You must set up your DNS servers so that email can be sent to your mail server.
One domain can have several names. These are also known as domain aliases. For example, your organization might own the domain, company.com, but it might also own company.org, company.se and company.de. If you want to be able to receive email for all these domains, you will have two options:
- Add all four domains to hMailServer. The problem with this is that you then have to add every email account 4 times, once for each domain.
- Add company.com as a domain, and then, under it, in the Names-tab, add company.org, company.se and company.de. That is, you add company.org, company.se and company.de as aliases of company.com. That, usually, is the route most users prefer.
On the signature tab, you can configure hMailServer to add a signature to all email sent from this domain. It's possible to enter both a plain text version and a HTML version of the signature. If no HTML signature is specified, hMailServer will use the plain text signature as HTML signature as well.
It is possible to use the macros %User.FirstName% and %User.LastName% in signatures. These macros will be replaced with the users first and last name as specified in the account settings.
Maximum size (MB)
If this value has been specified (is not 0), the system administrator and the domain owner will be prevented from adding accounts so that the total size of all accounts exceeds this value. If you have specified 500MB, the total size of all messages in the domain will not exceed 500MB.
Maximum message size
If specified, hMailServer will reject messages larger than this size.
Maximum size of accounts (MB)

Using these settings, you can limit the number of accounts, aliases and distribution lists server administrators and domain owners can create in this domain.
This tab contains the advanced settings for the domain. You normally don't need to modify these settings.
If you specify a catch-all address, hMailServer will forward all email with invalid recipients on the domain to this account.
