  • Sendmail relay configuration on AIX | Leave No Bit Unturned – This document describes how to set up a Sendmail e-mail gateway or relay which will be able to process incoming mail and route it to different mail servers based on domain information. The routing table is based on the Sendmail mailertable feature instead of the usual MX record based routing. This will come handy when there is a need to route mail internally in a different way than externally.

The API for modules is open allowing arbitrary modules to be written to allow access to any data store.
    Perdition has many uses. Including, creating large mail systems where an end-user's mailbox may be stored on one of several hosts, integrating different mail systems together, migrating between different email infrastructures, and bridging plain-text and SSL/TLS services. It can also be used as part of a firewall. The use of perditon to scale mail services beyond a single box is discussed in high capacity email.
  • DeleGate Home Page (www.delegate.org) – DeleGate is a multi-purpose application level gateway, or a proxy server which runs on multiple platforms (Unix, Windows, MacOS X and OS/2). DeleGate mediates communication of various protocols (HTTP, FTP, NNTP, SMTP, POP, IMAP, LDAP, Telnet, SOCKS, DNS, etc.), applying cache and conversion for mediated data, controlling access from clients and routing toward servers. It translates protocols between clients and servers, applying SSL(TLS) to arbitrary protocols, converting between IPv4 and IPv6, merging several servers into a single server view with aliasing and filtering. Born as a tiny proxy for Gopher in March 1994, it has steadily grown into a general purpose proxy server. Besides being a proxy, DeleGate can be used as a simple origin server for some protocols (HTTP, FTP and NNTP).
