Something serious just started happening. My server is suddenly queuing many messages, even to those domains that we previously never had problems with (yahoo, juno, road runner, etc.). What can I do? Could this happen if the upload bandwidth of our DSL is overloaded?
I am running version 5.05, could an upgrade help?
P.S. ~ In the Summary/Filter section of the Mail Queues, the origin IP is shown as 127.0.0.1. Is that right?
