I am using UIM8.51 and i have configured email gateway. But some time i am seeing queue being built up in emailgateway
Also i am seeing older mails are coming, but my configuration is that only on arrival on the AO profiler.
Not sure why old mails are coming again and again. Please help me to sort out the issues.
I would suggest to you for this question that you open a support case for it that it can be investigated by the CA Support Team.
