As a Linux / Unix engineer with 10 years of experience working with projects, SMEs and enterprises - I can complete your project to a very low price in order to gain good reviews.
I can setup a sendmail/qmail/postfix/exim mailserver, with control panel if you want, and SSH / telnet or rlogin over stunnel/IPSEC for remote access, and a firewall filter so only your IPs can access those services. Please contact me so I can get started.
