Domain Maps
Domain maps give you the power to control how particular domains are handled and can be used to serve multiple purposes. They allow a server to be configured to act as a backup server, a relay, to create static routing for domains, to convert multiple domains into just one and much more. These domain map rules are applied to all incoming mails (SMTP and WebMail) before they are processed for local or external delivery.

  • Domain - When you first create a domain map, this is the text box where you enter the domain which is being mapped (ie code-crafters.com).
  • No Conversion - This turns off the Redirection / Conversion rule.
  • Convert Email Address - All emails addressed to the domain will be redirected to this email address. This email address can be a local address or external address.
  • Convert Domain - This allows you to combine multiple domains or just directly convert one domain into another (eg. if we setup our mail server to convert code-crafters.co.uk into code-crafters.com, sales@code-crafters.co.uk emails would be delivered to sales@code-crafters.com).
  • Additional Re-send Attempts - This only applies if the received mail is to be placed into the outgoing mail queue. This is commonly used in backup server configurations and allows you to increase the holding time for emails. This value is added to the value on the Outgoing Mail settings and allows you to increase how many attempts mails to this domain will be given when sending to an external account.
  • Use Normal 'Outgoing Mail' Settings - This only applies if the received mail is to be placed into the outgoing mail queue. This ensures that if this mail is to be sent to an external account, the normal Outgoing Mail settings will be used.
  • Via SMTP - This only applies if the received mail is to be placed into the outgoing mail queue. This option allows you to specify what SMTP server the mail should be delivered to (for static routing). Regardless of your Outgoing Mail settings (as long as the Outgoing Mail service is enabled). This SMTP will always be used for emails to this domain.
  • Visible to Incoming SMTP - During Incoming SMTP email transactions, each destination email address is filtered to ensure that no unauthorized email addresses are accepted for relaying. Enabling this option will ensure that any email addresses to this domain are accepted on the Incoming SMTP.

Please Note: The domain mapping rules are applied to the incoming mail after the mailing list rules. This means that addresses added to the email as a result of the mailing list rules are still affected by the domain mapping rules. If any of the email addresses in the email are affected by the domain mapping rules then the email is then reprocessed against the mailing list rules. This cycle will continue up to 200 times or until the email is no longer affected by either the mailing list rules or the domain mapping rules. This makes Ability Mail Server very flexible and also gives you the option to create very complex mail routing paths if required.
