How to configure a remote mail server

How to configure a remote mail server

This article explains how to use the SiteWorx Remote Setup feature to disable local mail delivery in order to direct your email traffic to a remote mail server. 


  • An existing SiteWorx account with the appropriate access permissions to modify DNS records. If you are not able to modify your MX record, contact your provider and ask them to alter the MX record or records for you. This may be the Nexcess Support Team, your hosting reseller, or your system administrator.
  • If you plan on changing the MX record to point to a remote server, retain the correct information for the destination mail server.


The instructions provided in this article are intended specifically for SiteWorx users. If you are a NodeWorx user, refer to How to modify MX records with NodeWorx.


  1. From the SiteWorx main menu, click Administration > Mail Options > Remote Setup.
  2. Under Action click [Disable] for the domain that you want local delivery disabled. 
    E-mail Management:  Disabling Local Mail Delivery
  3. When prompted, click Disable to confirm.
    • If you are only disabling email for your domain, stop here.
    • If you need to configure email to point to a remote mail server, continue to Step 4.
      4. Under the MX Records section, click [Edit].
      5. Enter the appropriate settings for your remote mail server and click Save.
    • TTL: Time to Live; the number of seconds that a record will be considered valid by a server caching the information.
    • Preference Number: An integer, ranging from 0-65535, indicating the order in which records should be attempted. Lower numbers will be processed before higher numbers.
    • Mail Server: The name of the destination server where mail traffic will be directed.

Using webmail with custom MX records

Once you have disabled local delivery and provided custom MX records, Web-based email programs provided by InterWorx will now act as IMAP clients, provided that IMAP is supported by the mail server.
