Take a look at my background and experience and you will quickly see I am the candidate for this project. In my day job, I work as an internal auditor doing these types of assessments several times a year. In my previous day job, I did email security assessments for many companies including companies in the US Fortune 500 and the Public Sector.
Additionally, I have over 18 years experience working with many different types of email servers / solutions such as Microsoft Exchange and many other Unix based email systems. I also have experience working with email filtering solutions that help to detect and limit the amount of spam/junk email and vulnerabilities that would end up in your users email boxes. Also, I have worked with several Secure Email solutions such as Zix, Proofpoint, Barracuda, IronPort MimeCast, and other for email encryption.

Look forward to working with you and you will not be sorry hiring me for this project.
