Appendix E. Email Hosting Settings in Service Templates

This section explains the email hosting features that you can set up in service templates. These settings act as default values: if permissions are granted, customers will be able to change these settings.

Name	Description
Handling of mail for non-existent mailboxes	Specify the mail bounce settings. When somebody sends an email message to an email address that does not exist under a user's domain, the mail server, by default, accepts mail, processes it, and when it finds out that there is no such a recipient under the domain, it returns the mail back to sender with an error message. You can choose to: Continue returning all such mail back to senders (the Bounce with message option). Forward all such mail to the specified email address (the Forward to address option). This is also referred to as a catch-all address. Forward all such mail to another mail server with the specified IP address using the option Redirect to external mail server with IP address (available only for Windows hosting). Reject such mail without accepting it. If the sender's SMTP client is behaving properly, it will generate a "Recipient address rejected: User unknown in virtual mailbox table" non-delivery notice (the Reject option).
Webmail	Provide users with access to browser-based Horde or Roundcube webmail.
Spam filter management	Provide users with SpamAssassin spam protection for mailboxes. This functionality is only available on Linux-based service nodes.
Antivirus management	Provide users with an antivirus for mailboxes.
