Just a couple of thoughts - as usual some of the answers depend on what someone what's to accomplish, what is their architectural preference, and what their bias is (bias is not always a bad word). We are heavy users of Domino - both for applications, calendaring, and email. Per our parent company we will be moved to Exchange 1Q 2006. Not that this is an indication of Exchange being better by any stretch. It's a corporate standard and the majority of the company uses it, we are one of the few Domino email users. Just to lay the groundwork for what I say. It's hard for me to quantify in technical terms but I am fully in the belief that Domino was a workflow application first and an email/calendar/PIM product second or even third. In my comparisons over the years I think that it is not the best mail server out there. Nor is the Notes client the best mail client. Right now I think they are both close to Exchange/Outlook and other email products. At a 50,000 view that is. Within the email world I think you can get into a lot of details and issues that can change that opinion either which way. But it is not a best of breed mail product, nor is it a bad one. If you are a Domino application user there is some benefit by also having it as your mail system. Not required but I think there is some synergy. So, would I use it as a mail server? Possibly, but if I did (as well as any other mail server) I would use a number of external resources so that some heavy lifting is external to my server. But I would do that with any mail server - that is my bias or architectural preference. I also think that for certain people running everything under OS/400 makes good sense. As well as those who want to fragment their processes to different platforms. There is no right answer. Personally, I just have issues with someone that slams every application onto their iSeries and those who distribute everything to any available Wintel or Linux platform. I think there are risks inherent to both of those approaches. The extremes are the ones that would worry me. In my world we put a preponderance of applications on the iSeries. We have examples of systems that might not have been a good fit. Fortunately, those have gone away with the advent of bigger/better/faster processors (WAS on a 720.......ran 80% of the application without a hitch, the remaining 20%.....gross). We also have examples of systems that we allowed to be distributed to WINTEL platforms and they have issues - warehouse management with Oracle......I'd never do that again. Portal on 6 Wintel servers - Never again - actually the good news is that it is going on WPS on the iSeries but again certain performance characteristics are risky. I think you have to be careful in using absolute terms and always remember that some people have certain other preferences. In a lot of cases they can be considered valid.

Totally untrue ... I dislike Domino for email because it doesn't appear to follow the RFC standards that modern email applications are supposed to abide by. Mailman is far from archaic ... it's quite modern and flexible. It can cope with a wide range of mail servers and clients ... so long as those clients play by the same rules. Most servers & clients do. Domino has some deficiencies in that area. > David, for the record, ENDDOMSVR < PWRDWNSYS(*IMMED).

What I am talking about is isolating the email function from the rest of your infrastructure because it is far more vulnerable to external influence / attack. For the record ... I also would not advocate running your mail server on a linux partition of the iSeries. The server is not isolated enough from your mission critical systems. > From the way this thread is going, the suggestions have been to find > an old clunky pc, install Linux and some open-sores email software > and call it a day. yeah right Nothing is as simple as that ... and you know it. > how is that going to get backed up? oh now you need to find backup > hardware and software.

We'll just have to agree to disagree on that topic. The same arguments you make, however, apply to ANY SYSTEM IN THE WORLD. If you don't provide the necessary infrastructure, you probably end up dead in the water. As most people know, there are two types of systems in the world ... those that have failed ... and those that will fail. As a side note ... there's absolutely no reason you can't have the linux system running with it's core file systems mounted via NFS *FROM THE ISERIES*. That way you have solid backup and failure protection at all times. Properly setup, the linux system could be as transportable as a bootable CDROM that has enough kernel code on it to boot up, start networking, and mount the necessary file systems. > Have you ever used Domino on iSeries?? A little ... not much. I'm not a big fan of the interface. I'm not saying Domino doesn't have good uses ... I know a number of very large organizations that use it heavily and are quite satisfied with it. I just think it's not the best choice as an email system. david -- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
