Project Description

As a small ISP with no in-house Linux skills, we require someone to configure a new Lunux and Sendmail based SMTP MTA/relay server.

- Linux CentOS basic config

- Sendmail (or equivalent) SMTP software

- milter-filter (or similar) for rate limiting customers to avoid being listed for spamming. Daily limits based on source-IP, sender domain and sender address.

- Sendmail open relay (no authentication) for internal IP range/block

- IP Tables firewall config (including only allowing TCP/25 to be accessed by ISP IPs)

- Sendmail Analyzer (or similar) web based reporting

- A web based interface to view and search for emails on the Sendmail log. Used by staff to trace/search for email problems reported by customers.
