    Configure Postfix server with SRS and postgresql
    I had a very good experience working with Mohamed. This job was a challenging one, and while it was completed unsuccessfully, Mohamed let me know from the outset where the issues may exist. Communication was superb throughout the process, and I felt like I knew exactly what was going on during the entire course of the job. Mohamed did an excellent job of letting me know where there were technical issues, what my options were, and his assessment of those options. Truly, I couldn't have asked for better communication. I would absolutely hire Mohamed again, and intend to do so if I require any more system administration needs.
