Hello, my name is Talha and I am pleased to offer my services as the best fit for this project. I have experience in deploying and maintaining many different types of systems, including cloud computing platforms, server operating systems, web servers and servlets containers, mail servers, database servers, virtualization platforms and directory service panels. Additionally, I have experience in monitoring systems such as Active Directory, OpenLDAP and File Server Systems.
I understand that you are looking to have an issue with mail relaying and signup security resolved in your Magento 1.9 installation. The issue itself is small in size and scope and I am open to suggestions for how to address it; at this point I do not have any sort of solution in place but would be willing to work through any possible solutions with you until a satisfactory conclusion can be reached. This is a security issue rather than a hosting issue so I believe that stronger CAPCHAs may be necessary to prevent automated signups from occurring on your website despite the existence of a capcha in place.
