Multiple NICs on Exchange 2007

Hello Experts,

I have a single all role Exchange Server 2007 SP2 that has 4 NICs installed. I have configured each NIC as a internal private subnet.

192.168.1.0/24
192.168.2.0/24
192.168.3.0/24
192.168.4.0/24

Our network consists of 4 subnets to decrease the broadcast domain via VLANs on the switch. Some of my users are receiving Event ID 5000 showing up. When I researched Event ID 5000, it seems that Outlook is having trouble trying to send email.

Would having 4 internal NICs cause end users from having trouble sending emails? The server is not doing any routing. Each NIC acts as if it were on its own subnet.
