Exchange 2007 CCR active node's apipa address of 169.254.1.x in email header

I've got an Exchange 2007 CCR active node's APIPA address showing up in the  email header of an outbound message. What I'm failing to understand is why it's showing up on the email header with same apipa address 169.254.1.41 of the Active CCR node. Why not use the cluster IP of the mail server which is 10.10.10.23. ? How do I correct his?

From doing some research I found some articles saying that the Microsoft Failover Cluster Virtual Adaptor assigns itself an APIPA and does this for each node in the cluster. I read that this is normal behavior but I'm a bit skeptical.

I just checked my old coworker email header from their exchange 2007 ccr and apparently it's normal for that apipa address to show up in the header.

the 169.254.* address is the default auto-config address range for NIC cards.

All NIC's will default to an address in that range if they aren't configured with a static IP address and cannot obtain an address from a DHCP server

As to why it's showing up in the email headers? That, I don't know
