Host-only network adapter causes conflicts, lies about disabled status

Description

After installing VirtualBox on my Win7/x64 machine, I noticed that I can no longer send email. Thunderbird produces the message "An error occurred sending mail: The mail server sent an incorrect greeting: 4.3.2 Connection rate limit exceeded.."

I had never seen this error before until installing VirtualBox, and the error started popping up immediately afterward. Unfortunately, disabling the host-only network adapter does not fix the problem. I actually don't think the adapter is disabled at all, though: the guest can access the internet just fine with it disabled. Connecting to a VPN fixes the problem, but the guest cannot access the network while the host is connected to the VPN.

Google turned up nothing, nor did a bug search. Bug #8698 seemed similar, though, and I tried changing the metric as advised in the comments there; no luck, the behavior persists. VBox.log contains nothing related to networking (just a ton of messages about seamless mode and window resizing).

I realize the true test would be to uninstall VirtualBox and see if the problem goes away, but that would undo many hours of work to get the thing running so I didn't try it.

Happy to try workarounds and/or diagnose further, but currently out of ideas...

What is the network attachment that the guest uses? Please, attach VM config - the *.vbox file. Do you have any mail software in the guest configured to access your SMTP server?
