I just did this in response to the dul blocking by AOL, et al.  I've
included notes below, but the setup at home is basically a custom domain
via DynDNS, i.e. I have mail for mydomain.com being delivered to a mail
machine.

I did not add this.   I simply added the domain specific lines below.


> rr.com smtp:[smtp.myisp.com]

I did add this (aol.com in my case).  Be sure to add another line for
the subdomains, e.g.

.rr.com	smtp:[smtp.myisp.com]

Yes.

Only if you want the outgoing mail to look like it is coming from
myisp.com.  As mine has other domains, I left out the masquerade.
