First, since you are using uucp, it means you are using rmail to transfer mail.
Because rmail does not currently understand @ addressing, you cannot get him to
send your internet address.

HOWEVER, if you and the site you connect to both run Smail 3.x, and the other
site is an internet site, you can use rsmtp, which performs a remote SMTP
transfer over UUCP instead of using rmail.  We use this to connect to one of
our forwarders, and you cannot tell we are a uucp only site from mail that
passes through there.

On the second question, you just need to ensure that the cost of using the 
crdgw1 link is cheaper than the cost of using the philabs link, via your
map entry file.  It would be sufficient to do something like:

nbc1  philabs(DEMAND), crdgw1(DIRECT)

This will make the crdgw1 link cheaper than the philabs link.  The last bit,
getting sun to always be expanded to sun.com requires a little sed'ing on your
part.  Pipe your pathalias output through the following command

  sed 's/!sun!/!sun.com!/'        

before directing the output to paths, so it looks like

  pathalias [options] | sed 's/!sun!/!sun.com!/' > paths

This will change all occurences of sun to sun.com in the paths file.  I do this
for uunet since our forwarder does not use uucp aliases.
