I started with computers when I was 14 and became a computer professional at age 17 when I wrote a real-time multi-tasking operating system for ship, pipeline and refinery control while attending Tulane University in New Orleans.

From there, at 19 I passed on jobs at Apple and Microsoft (in '83) to join Digital Equipment Corporation where I helped found two support businesses for them.

I then joined Relational Technology Inc. (later Ingres Corp), and, as a direct report to the Sr. VP of Sales, performed just about every technical role in the company, curriculum development, consulting, technical support, development, benchmarking, created Demos, represented the company at trade shows, etc, and I even helped sell the product.

After a while as an independent consultant, Professor Michael Stonebraker invited me to lead a research team at UC Berkeley's Electronics Research Laboratory wherein I developed the world's first "Grid" computing system - which was also the first truly heterogeneous distributed computing system, today known as "cloud computing."

In '97 I commercialized the work and founded several companies where today I have a split life as "executive" and technical wizard - in short, I serve as chief cook and bottle washer. I'm a jack of trades, and specialize in computing performance and heterogeneity with an eye toward production work, stability, maintainability and up-time performance.

In the last few years I have become involved with life-sciences computing, and last year served as CTO / VP Engineering of a company bringing health-information to the masses, but unfortunately that venture folded due to what I will politely call, "capitalization issues."

comment postfix pop-before-smtp isn't parsing the log correctly - need PERL help, I think
Sorry, but when you say "which you haven't done," you're wrong. The problem was solved a few days ago. You know, condesention to people you're writing to / about isn't flattering to one's self.

@DavidCaccavella OOPS! After writing the update to my answer I just posted, I re-read your question and just realized I thought you were coding in PHP, but if it's an ajax front end, then switch to use JavaMail!

The comment I made to proy above applies to your answer too; Of course, you didn't answer the question at all, but what you perceived as the meta-problem. And, I was already onto SASL, however SASL wasn't working, it wasn't certain why, debugging was happening, and when you hit one road-block, you head for another route until the primary one clears.

comment iptables masquerading / NAT firewall works with IPs, FAILS on SOME connections, esp when Domain Names are involved
Thank you, but unfortunately I don't understand how it's blocking those out-bound queries. Any thoughts? Is there some aspect of networking external to iptables that I may have overlooked to configure (or got configured wrong by NetorkManager before I turned it off)? BTW, I tried it with UDP too, and it didn't work either - same result.

Your suggestion did gain new data as I hadn't tried DIG on it previously; the DNS server says it's refusing the connection.

You appear to be mistaken. Both the gateway and the test system behind it have their DNS set up correctly. The DNS servers all respond correctly from a system that can "see" them (not behind this firewall). Further, if I switch the test system to a different (identically ??) configured gateway, it works fine. I'll update the main question with example data.

comment Running applications in Tomcat without unpacking WAR
Doah! What was I thinking? -shrug- (At the moment I can't quite recall what file type I was thinking of.) Ah well, I'll blame it on lack of coffee at the time! -wink-

You might want to update your tags to include windows as WAR files are Windows-specific (Windows only).
