According to rpmfind.net, libssl.so.4 appears in openssl-0.9.7a. Is that
installed on your system? Was that listed as a pre-requisite by whoever
built the RPM for you?

Google is your friend --

http://www.faqs.org/docs/abs/HTML/exitcodes.html

return code of 126 means that the specified file is not executable. Is
/bin/mail executable by the nagios user on your system?

Correct for your installation maybe. I have mine in the standard
location of /usr/local/nagios/libexec. A return code of 127 means that
the command you are trying to execute was not found. Verify that the
$USER1$ macro in resource.cfg points to /usr/lib/nagios/plugins and/or
that your command definitions in commands.cfg are using the $USER1$
macro or have the full path to the command specified. Depending on who
built the RPM, those may be incorrect.

There are copious amounts of documentation on http://www.nagios.org that
will likely be of value.
