INFO: MailMarshal (SEG) Cloud Connection Details (Europe)

 

This article applies to:

  • MailMarshal (SEG) Cloud (EU instance)
  • For other instances, see article 21095 (US instance) and article 21149 (Australia instance)

Question:

  • What are the addresses to send mail through MailMarshal Cloud (EU instance)?
  • What are the URLs for MailMarshal Cloud consoles?

To open the MailMarshal Console navigate to https://console.eu.mailmarshal.cloud

  • Customers use this Console to manage email and settings.
  • This site is available over both IPv4 and IPv6.

In This Article:

This article provides the technical details for connections to and from the MailMarshal (SEG) Cloud service for the EU instance.

Inbound MX Record

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

MX Record Priority
mx.eu.mailmarshal.cloud 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
smtp-outbound.eu.mailmarshal.cloud
  • You must allow connections on port 25 from your local email server to this server name. Cloud email providers (like Microsoft and G-Suite) can already connect to this range.

IP Address Ranges to allow

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

Port 25 is the only supported port for delivery inbound.

Address Range
52.143.19.192/28
51.104.163.144/28
2602:f8d5:a6:1::/64
2602:f8d5:a6:8001::/64
  • 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:
include:spf.eu.mailmarshal.cloud

For example
v=spf1 include:spf.eu.mailmarshal.cloud -all

SPF Record Include Text - Office365 Customers

If your email service is hosted on Office365, also include the Office365 SPF record:
include:spf.eu.mailmarshal.cloud include:spf.protection.outlook.com

Note:

The "mailmarshal.cloud" names are the default going forward. Trustwave recommends that customers update their DNS and settings, replacing any previously configured values. Existing previously notified values continue to work, but may not have new functionality added (such as DANE).

  • For customers using the SQM Single Sign On feature, the SSO URLs must be changed to refer to the "console.eu.mailmarshal.cloud" domain.
