I have 2 SharePoint 2013 WFE servers with a Cisco CSS VIP load balancer. I have applied service pack 1 and may 2014 CU.
I have configured the basic scenario incoming email on both servers as per this article http://technet.microsoft.com/en-ca/library/cc262947(v=office.15).aspx.
My MX records are pointing to the CSS VIP (the Cisco load balancer). Emails are delivered successfully to a the Cisco load balancer which routes the emails to the one of the two servers. The only problem is that sharepoint picks up the emails from one server only and not both. If I run the "Timer Service recycle" job and kill the first server, sharepoint starts picking up emails from the other server.
What could go wrong? is there any additional configuration needed so that sharepoint check both servers?
