You need to tell your email server that it should masquerade as "home.com".
Moreover, you should direct it to TryNullMX (sendmail instruction) that is,
do not reject with a "mail loops back to me". Now I assume that the "home.com"
is really some other domain, because if it is home.com, then it is a very bad
idea for the mail server to masquerade as it.
If you are on home com, then make your hostname something else and masquerade
as that something else. I use nwarctic.yi.org as a masquerade and I simply
registered at yi.org for that fqdn. I was also able to give them my static IP
and make sure MX records bound for nwarctic.yi.org reach that address, without
actually exposing my IP to hacks, CNAMEs, reverse lookups,
host -a nwarctic.yi.org
etc.
