Question:

How do I change the MailMarshal HELO name?

Comments:

It is possible to change the default HELO name that MailMarshal uses.

• The HELO name MUST be a valid Fully Qualified Domain Name such as seg.example.com (do not use a server name or a .local domain suffix)
• The HELO name should match the From address of outgoing email if possible (seg.example.com is a good choice of HELO name when sending email from ...@example.com)
  
  • This will not always be possible since some servers send email from more than one domain
• The PTR record for the IP address should match the HELO name (Again this may not always be possible)

All of the above could be used by email servers to validate the source of email.

Procedure:

This is a Node-specific setting, and it may be necessary to configure each node as desired.

For MailMarshal (SEG) 10.X:

1. Open the Management Console.
2. Select Management > Mail Servers
3. In the right pane, select a specific server and then click Edit.
4. On the Advanced tab, enter the desired HELO name in the Server Host Name field.

For MailMarshal (SEG) 8.X:

1. Open the MailMarshal Configurator.
2. Select Server and Array Configuration > Servers
3. Edit the specific node or server.
4. Enter the desired HELO name under Advanced | Server Host Name.

Notes:

•  You can also change the server name and version information in the message headers and greeting string (used when receiving mail). See Trustwave Knowledgebase article Q10436.
