We've had ongoing problems downloading pop3 from our servers. We're essentially on the IS network, and downloading email from anywhere else has always been slow. This morning was particularly bad, though. It took me 30 mins to download 1mb of email from a Telkom internet 1MB ADSL connection and I actually gave up in the end when it started timing out on the last email. It's definitely protocol/packet shaping as I can access the same server via http on a webmail interface quite speedily.
You've got to be joking, whats next? In about a month theyll probably start shaping http and then nothing will work but at least their network wont be "congested". This is bull****.
