We've configured incoming mail to come in to one of our WFE servers, and this work correctly. However we'd like the mail to be sent to the NLB VIP so that it's redundant across our 2 WFE servers.
But the incoming mail timer job only runs on one server at a time, until the Timer Recycle job flips it to the other server, which runs once per day. This means if the incoming mail timer job is only looking at WFE-01, any mail sent to WFE-02 would not be collected until the following day, and vice-versa.
From what I understand SharePoint 2010 ran the timer job on a round robin on all servers running the incoming mail service, which makes sense. This seems no longer the case for SharePoint 2013, and looks like a bit of a backwards step.
Has anyone managed to get incoming mail working across multiple WFE servers in SharePoint 2013?
