Good thing you explained that, I almost sent a reply after only reading the
first line.... =)

Not all ISP's mail servers are only a few hops away.  Smaller ISP's tend to
outsource their mail servers (e.g. - C2I2, traceroute is blocked after 18-20
hops(yes it varies)) and larger ISP's may have their mail servers located in
another part of the country.  The only thing you can do to protect yourself is
to not reuse passwords (the password you use to get email is only used to get
email from that one server).
