User Web profile documents
User profile documents are an essential tool if you are planning to build any serious Web application. Whether it is color schemes and style-sheets or language and timezone settings, most Web developers need a method of keeping track of individual user preferences. This article, the third in Daniel's series, extends the techniques from the first two articles to allow you to create individual user profile documents by adding the ability for each user to select their own preferred calendar language in the Domino Web popup calendar application. [DominoPower Magazine, October 2004]

Managing database ACLs from a browser
This is the fourth installment in a series of articles designed to make the task of developing Web applications for Domino a more pleasant and efficient experience. Contributing Editor Daniel Koffler has already shown you how to create a pure Domino Web popup calendar to assist users in selecting dates on the Web, and how to create both global and user profile forms suitable for use on the Web.

Build a Domino pop-up calendar widget using formula language
Although available when programming for the Lotus Notes client, Domino does not provide any built-in widget or applet that lets Web client users easily select a date from a calendar to fill in date-based fields. As it stands, most Domino forums and programming guides advocate installing a 3rd party JavaScript or Java applet-based calendar. This is wholly unnecessary as the Lotus Formula Language has amazing date handling functions that will let you easily build a customizable and reusable popup calendar in any web accessible Domino database. This article by Daniel Koffler takes you through all the steps. [DominoPower Magazine, September 2004]

Global Web profile documents
Even though Contributing Editor Daniel Koffler is a long time advocate of designing Web applications in Domino, he's developed a few pet peeves over the years. The biggest of these is the fact that there are a host of features that have been available to developers targeting the Lotus Notes client for years that are still not available in the browser. This is the second article in a series that intends to fill your toolbox with re-usable widgets, code-snippets and tips that will make programming Domino Web applications into a friendlier experience. [DominoPower Magazine, September 2004]

Hacking Domino mail rules to fight spam
Have you ever wished Domino's mail rule system had more power? Wouldn't you love to be able to create server mail rules that can act on messages tagged by 3rd party products such as Spam Assassin or be able to create white-lists for use with Domino's built in DNS blacklist feature? How about processing SMTP messages based on the hostname given in the helo/ehlo command or based on the source IP of the sender? All these features and more can be yours with a little creative hacking of Domino's existing mail rule system. [DominoPower Magazine, December 2003]

Prevent spammers from abusing your Domino systems
Nobody wants spam in their inbox. Getting spam cuts into user productivity, uses system resources, and tends to generate many help desk complaints.

There are two major ways spam can wreak havoc on your Domino infrastructure that won't generate a single user complaint until it's too late and they're described in this important article. [DominoPower Magazine, September 2003]
