I don't know if the code in the application I work on is the OLDEST... but some of it was last modified in 1993 and has never been recompiled since. Still runs perfectly. Started on a 48bit CISC system and now runs on a 64bit RISC system.
The application runs on a IBM i (formerly System i, formerly iSeries, formerly AS/400).
Can't remember - was MRT (instead of SRT) not supported under Cobol, then? Was in RPG... Aren't MRT's specific to the S/36?
I've never seen a MRT in i5/os (os/400).
That said... after a program is loaded into memory, any subsequent invocations of the same program use the same code. The data storage area is different, but the code is the same.
9) Service contract: 60 machines for Dell vs 1 for IBM. Does the AS/400 support cost 60 times more for the same level? I'm guessing, no. AS/400 wins. Dell might not even offer service contracts for the machines you're comparing (hard to tell since you never mentioned which ones).
Not to mention the level of support... with Dell, chances are you'll end up with some level one support rep out of India who can read scripts. With IBM AS/400 (System i now, don't talk to me about the naming) you'll spend 2-3 minutes with a support dispatcher, and then you'll be transfered to a highly trained, and product area specializing, support rep out of Rochester MN or Toronto Canada... this support rep will not drop the request until your problem is solved. You'll know the name of the support rep and their direct phone number. Oh yeah, the support rep will have direct access to the appropriate developers for the problem area. When the problem is resolved, you'll probably get a follow up call from IBM customer service to make sure you were satisfied with the resolution.
Yes, a System i / iSeries / AS400 is probably more expensive than a Dell... but in this case, you absolutely get what you pay for.

... find the ERP system that does everything you need (well, as close to everything that any ERP system can do, all businesses are somewhat different such that the ERP system needs some tweaking). Don't make software decisions of that nature based on what systems it runs on.
Once you find the system that's right, then determine what platforms it runs on.
If it's windows, take prudent precautions... make sure you have plenty of redundancy and virus protection.
Personally, I'm a big proponent of iSeries. Nothing can beat the system for stability and security.
Keep in mind, of course, that the iSeries isn't a legacy system that can only run RPG, COBOL, and the like. Current versions of the iSeries can run modern Java apps, Linux apps, AIX apps, PHP in Apache2, etc.
Of course, the even with the native applications (RPG & COBOL), you have solid investment protection... as you almost never need to change an application due to a hardware or operating system upgrade.
IANAL... but I don't think that an NDA can prohibit you from listing the project. It can prevent you from disclosing information about the project, but that's it.

Pick 1 or more of the following...
Run some java apps on it... there is a full blown Java2 1.4 VM available (what better platform to run a Java VM on but one that implements the concept of VM at it's core)
Run Linux apps -- Suse, Redhat, & TurboLinux (I think) distros available to run in a logical partition
Run Apache2 web servers
Run AIX apps on it
This ain't your father's AS400... it's one of the most stable & reliable 64bit computing platforms available.
btw: Did you know that when IBM changed the CPU on the AS400 from a 48bit CISC system to a 64bit RISC system (PPC based) there was almost zero application programming changes required... the programs were able to adapt to the new capabilities of the hardware automagically.
Now that CAN'T be enforcable. Once you leave a companies employ, they have no rights to what you do.
Additionally, considering your next employer will probably have rights to everything you create then, your previous employers contract would be in direct conflict.

No argument ... iSeries isn't a hackers box ... but the original request was for TECHIE lists. You can get plenty technical on the iSeries.

So is there any documentation describing a good way to convert from sendmail? Like, how the directives in sendmail map to directives in postfix?

I mentioned to some bigwig at SCO that some code in the Linux kernel looked a lot like SCO's unix. :)
It doesn't HAVE to be so ... it just is.
Get some Apple UI developers to pitch in on the user interface and that would probably change.

They are eating up resources that we, or our customers / users, should be rightly using.
How do you stop a DoS attack? You block the offending IP's.
That's what the block lists allow mail server operators to do.
