Inbound MX Record

To have incoming mail delivered through MailMarshal Cloud, set your MX record as follows:

MX Record Priority 10
  • You (the customer) or your DNS provider must make this setting.
  • Make sure you only have one MX record. If you have more than one record then email might bypass MailMarshal Cloud.

Address for outbound mail

To send outbound mail through MailMarshal Cloud, use the following server name.

Server Name
  • You must allow connections on port 25 from your local email server (or cloud email provider) to this server name.

IP Address Ranges to allow

Inbound messages from MailMarshal Cloud to your servers may originate from addresses in the range noted.

Address Range
  • Ensure that your internal email system always accepts messages from this IP range. You might need to configure exclusions for Connection Filtering and IP Reputation services so the MailMarshal Cloud IP addresses are never blocked by these services. For help with email system setup, see documents found on the MailMarshal Cloud documentation page.

SPF Record Include Text

To include MailMarshal Cloud in a SPF record for your email domain, use this text:

For example
v=spf1 -all

SPF Record Include Text - Office365 Customers

If your email service is hosted on Office365, also include the Office365 SPF record:

Console URL

Customers use the following URL to connect to the MailMarshal Console for email management and rule management:

The "MailMarshal.Cloud" names are preferred going forward. Trustwave recommends that customers update their DNS and settings, replacing any previously configured values. However, existing previously notified values continue to work.

The default URL domain for the MailMarshal Console is now updated to "Console.EU.MailMarshal.Cloud" and all web requests will be redirected to this domain. Links and bookmarks to previous domains will continue to work. Email flow is not affected. 

  • For customers using the SQM Single Sign On feature, the SSO URLs must be changed to refer to the "Console.EU.MailMarshal.Cloud" domain.
