Thanks for the answer. A few weeks ago our network manager installed a intrusion
detection/content filtering device that inspects all traffic passing through our
network. The device acts as a transparent proxy, and apparently buffers the network
traffic so that it can scan it for malware. I'm hoping that this device has been
the cause of these problems. He's disabled scanning for POP3, so I'll keep an eye
on it for the next few days. For the benefits of the archives I'll followup if this
was the solution. Thanks again...
