Upwork ClientNurul was flexible and easy to work with. He was responsive and got the job done quickly. He communicated well and showed deep competence in both Postfix and Exchange - and we did have a number of issues to work through. Actually Nurul went above and beyond my requirements, suggesting further configuration improvements that I would never have known I needed. I can recommend him highly.
