Hi,
I have 12+ years of experience on Linux and Windows servers especially built on VMware and Microsoft Hyper-V platforms.
From project description, I understood that you want to setup a mail server. Have you decided which product you want to use? I personally suggest to go for sendmail as it is most robust system I have ever worked as open-source platform. Have you created MX record and A record already?
I am specialized on system administration, design, deployment and troubleshooting.
I believe I would be an ideal candidate for this job.
Regards,
Shafiul
