Justin,
The only file you should need to edit (other than DNS) to add a second
domain to sendmail is your local-host-names (sendmail.cw on older
sendmails). This tells sendmail what is in the class w or which domains are
local and which domains would be considered a relay. The relay-domains file
tells sendmail to allow everyone to relay for a specific domain. That
feature is used to allow relaying for secondary MX records or proxying mail
to another host on the trusted network.
You shouldn't need to make any changes to your sendmail.cf and I would
recommend using the m4 method and changing the sendmail.mc and compiling a
sendmail.cf from it. While it is a little awkward at first, but I think it
keeps the config file much more manageable.
While looking at your config I would remove the domains from the access file
because it will allow anyone who can setup their reverse DNS to any of those
domains to relay. The last line is all you really need. I would also
remove all of you domains from your relay-domains file because you are
declaring them as local in your sendmail.cw. One last thing, I recommend
that you put the fully qualified domain name in your sendmail.cw that way
you can accept mail addressed to user@fqdn.
Hope that helps,
schu
