Bug Fixed:

[ERR] switch_cpp.cpp:1465 [database] can not bind parameter: undefined parameter: email_from

Edit /usr/share/freeswitch/scripts/resources/functions/send_mail.lua

if (email_from == nil or email_from == "") then
        email_from = settings:get('email', 'smtp_from', 'text');
        from_name = settings:get('email', 'smtp_from_name', 'text');
end

-- fixed: [ERR] switch_cpp.cpp:1465 [database] can not bind parameter: undefined parameter: email_from
email_from = 'noreply@your.domain';

if (email_from == nil or email_from == "") then
        email_from = address;
elseif (from_name ~= nil and from_name ~= "") then
        email_from = from_name .. "<" .. email_from .. ">";
