What’s Websense? We dropped Yahoo last year.

Beats me!

This is the first time I've ever heard of websense.

However, the problem appears with Yahoo e-mail and Hotmail.

From what I could quickly gather from a Google lookup, it's an organization that takes it upon themselves to block sites they deem to be harmful.

Websense is a filter that categorizes websites so that sys admins can block web access on their networks.

Sys admins usually block email access to prevent staff from downloading attachments with viruses.

You mentioned it affecting one machine, but not another. Are these on the same network?

Websense is usually applied via a proxy, a device your connection to the internet is routed through to help prevent access to your local network, scan for viruses, and in your case limit web connectivity so that staff are working instead of surfing.
