Advanced Perl Developing, by Sriram Srinivasan (Anonymous, 1997) has a good section on developing network servers.

Effective Perl Developing, by Joseph Hall with Randal Schwartz (Addison Wesley, 1998) is a useful tutorial for picking up Perl idioms.

http://www.cauce.org/ is a site from Coalition Against Unsolicited Email. There are many sites devoted to fighting Unsolicited Commercial Email; this site is a good place to start. It has pointers to many other sites, including those that go into greater detail about the analysis of mail headers for this process.

http://www.eudora.com/developers/scripting.html contains information for scripting Eudora with pointers to other AppleScript references.

http://www.microsoft.com and http://msdn.microsoft.com have information on "MAPI," "active messaging," and "CDO." The name of this technology has changed twice so far, so I'm hesitant to give you a specific pointer. There is plenty of good information at the Microsoft sites (especially in the MSDN library section) on these topics, but it tends to move around a bit.

Perl tutorial, by Tom Christiansen and Nathan Torkington (Anonymous, 1998), also addresses the developing of network servers.
