The Eskimo exchanger is sendmail based I believe and he is just spooling
for my domain.  He forwards via smtp.  Yes I have an imap account at
eskimo.com, but that is an eskimo.com email address.  Perhaps
eskimo can figure out a way to deliver robinson-west.com email in an
emergency from the backup spool to say an eskimo.com email address.  I
need to look into UUCP, something that came up as a possibility for
getting around a mail exchanger outage caused by a DSL outage.  I'm not
only interested in being able to access my email for robinson-west.com
off site in an emergency, I'm also interested in traffic control so that
the DSL line doesn't get congested.  Even if I had a 100 mbps/3 mbps
Internet connection, increasing popularity will eventually take it down.

Speaking of traffic control, I'm trying to set up webalizer with a
custom compile of Apache 2.4.10 and can't figure out how to configure
Apache for webalizer.  My documentroot is /var/www/robinson-west.com.
Any thoughts on why I get file not found from firefox?  Googling isn't
helping, seems the howtos that are around mostly focus on Apache 2.2.x.
Apache 2.4.10 is very different and I think even if you are running just
one web site that you have to look at virtual hosting to get webalizer
to work.  Webalizer should be a useful tool to confirm that I have or 
do not have a congestion problem.

I am on a Centos 6.x system and would like to have an init script that
works for Apache.  Currently I am just using the apachectl command
directly.

Another service I need to be concerned about, I host an ftp site using
vsftpd.  I have many Linux distributions available for download.  I need
to limit how much bandwidth random people can use and I should probably
limit random people to using 128k max of my upstream speed.  

The DSL connection is a 6M/512k one I believe, though the upstream speed
may be less than that.

In short, I like the privacy of hosting my email on a single DSL line
where I live.  There isn't much bandwidth though and the single point of
failure issue is a growing issue.  I can't solve the single point of
failure issue by having a single Internet connection that is merely
faster.  Single point of failure can only be solved by hosting a site at
multiple geographic locations where a service outage is not likely to
hit all of those locations simultaneously.  This means that I need to
learn a new way to set up email than what I do currently and have done
in the past.  Maybe I need to use the Zoho service.

The DSL modem supports something called QoS, but I think it is only
capable of marking packets so that even if I know what settings to put
in to make appropriate marks, I still have to reprogram my servers to
actually use those markings.  Whether that involves using the ip tool or
iptables server side, I'm not sure.

I'm simply going to have to call Eskimo tomorrow and see if I can match
their hosting services with what I need better.
