How Nexcess clients on non-cloud accounts can use the SiteWorx Remote Setup feature to disable local mail delivery. 

What you need

  • This method is only available for Nexcess clients on shared physical (non-cloud) accounts. 
  • If you plan on changing the MX record to point to a remote server, retain the correct information for the destination mail server.


  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 Disableto 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.
