It seems that my wlan card (intel 5100 AGN) firmware doesn't allow "spoofing" MAC addresses. This has the side effect of destroying the capability to bridge out my virtual machines on that interface. Apparently this is a common thing on wlan cards.

I can see the incoming traffic just fine in my virtual machines, but their DHCP queries don't get bridged out of the WLAN card. It works perfectly well when using the wired ethernet port.

Is there a workaround for this? MAC-NAT or something?

I don't want to route my virtual machines out to the Internet because I don't want my host OS to even have an IP address.

I'm using Linux and KVM for virtualization.

I'm looking for an imap server that is fast with larger folders. Say 20'000-100'000 emails per folder.

Currently I'm using dovecot, and opening a folder can take 10 seconds, and the HD light on the imap server is brinking like crazy.

I'm using alpine as a client, and it only lists the newest mails by default, so it's not that my client is trying to transfer everything when opening the mailbox. This can be seen in that when I scroll it has to load the subject lines for the next page (the first time I scroll there).

I'm using maildir on XFS.

Edit: I ask since it's not much data, in the grand scheme of things. If this was in a SQL database then getting the subject lines of the newest 40 messages would not take 10 seconds for a folder of 40'000 emails. The only data needed is:

SELECT date, from, subject FROM emails ORDER BY date DESC LIMIT 40;

Any ideas?
