Hi,
My name is Armen, I'm 33 and last 10+ years I've worked as system administrator. Install of a mail server, configure it work with phone(+web interface and pc mail client configuration) is about 2-3 hour work, ready to do job in 1 day maximum. I just need technical details(server os, mailboxes names) decide which one mail server are we installing(after that I'll know server os, I'll write you same versions of mail servers with tecnical compile details) and when all tecnical details will be comfirmed, you will get your working mail server in 1 business day.
will be happy receive possible feedback after work is done ;)
