#2 Change default Sender_Addr to null sender <>
Mail::CheckUser defaults to a sender address of
check@user.com . This is not friendly behavior towards
user.com.
A more correct default would be the null sender
address, <> . This patch changes that default
behavior. It includes a documentation update.

I should have added, use of forged sender strings can be
cause for a server to be blacklisted. This patch will
prevent a web server from being blacklist if one user of it
forgets to configure a sender address for a script.
I am also working on a patch for Net::SMTP that will change
the default HELO string from localhost.localdomain, which
can also cause a server to be blocked.
This came up today due to a listing at cbl.abuseat.org
