However, this is not a Microsoft Windows app, so the installer isn’t in play

set up the looking glass/router proxy, so it should be reasonably safe.

You still get a nice performance boost with 802.11b/g/n in 2.4 range
even at 20mhz, but if you go to 40mhz, you'll be splattering all over

it was a DNS server that ran on a Cisco Router, and could use a lot of

I see no major problems to use anycast for that.
The problem will be in rare case when particular routing chain from
client to one of your servers will be changed until TCP stream is active.
SMTP have short connections. Even if it happens, it will look as just
broken connection for client, and it
>but 'well behaved smtp clients' should already be falling back right?
If you have multiple SMTP servers at the same priority, it's a pretty
broken client that doesn't try them all until one works.
That said, there is a depressing number of pretty broken SMTP clients.
