I did not see the original question, but thought this might be helpful to some: Earthlink will block any email from any server that does not have reverse dns properly configured. For example, Sprint currently does not support setting up reverse dns properly for their ADSL customers, so we have to forward our email through a smarthost. Since Earthlink and Sprint are partners with DSL, Sprint directed me to have Exchange send all email to smtp.earthlink.net. This resolved our email issue. We have Symantec Mail Security for SMTP Gateways, which will allow us to route through the smarthose for only those destinations that we have problems with. This allows us to use DNS for everyone else that normally works. There are other programs out there that will do the same thing. Do not try to contact earthlink about any email issues since most of their tech support is clueless.
