Remember that I confessed to being a Sendmail, Inc. employee... Regarding replication, take your traditional sendmail/POP/IMAP server and add rsync. Stir vigorously, and you can probably get most of what your want from replication for your existing platform. A reliable nightly sync might meet most of your needs _without_ having to invest in a completely new mail infrastructure... Don't forget the cost/ benefit tradeoff.
Things like EMC appliance-based replication are expensive and have distance limits. A site I worked with recently had to scrap plans for a data center halfway across the country because the EMC-based replication wouldn't work with that much lag. YMMV ;^) Trying to supplant all the functions of Exchange is a bit trickier. The Steltor product is very good, though I've only gotten that at second hand. We've pitched it in combination with our products when people are looking for an apples-apples vs. Exchange. My opinion, Notes sucks as a mail platform - it may do great things a workflow platform, but if you're just looking for mail+PIM I wouldn't go that route. If you're looking at it for other reasons you'll be sorely tempted to use it for all mail, and you'll learn to live with the lousy gateways, etc. We do a lot of installations putting Sendmail Switch in front of Exchange and Notes to provide flexible routing, spam filtering, virus checking, and often delivery rate throttling... <plug> Sendmail has an extremely robust enterprise/ISP grade POP/IMAP mail store, the Sendmail Advanced Message Server (SAMS) available for many popular *NIX platforms and NT. It supports several hundred to tens of thousands of users in one or many domains, depending on the underlying hardware. Includes proxies that allow you to spread users across multiple servers for better load handling. The Sendmail Mobile Messaging Server (SMMS) provides Web and WAP interfaces to _any_ IMAP mailstore. Sendmail Switch gives you distributed management and configuration on top of the core OSS sendmail MTA. Nice GUI interface lets you specify configurations w/o dealing with m4, with extensive help describing all the features. Then use the console to deploy/update configs on local/remote clusters of MTAs - all Gateways get the same config, all Internal Relays get the same config. Have a mix of Solaris and Linux MTAs in each cluster - no problem. All management is handled over a TLS connection that's always initiated from the console, to allow for placing MTAs on a DMZ/external network. Right now, Sendmail Inc doesn't offer a calendar. But Stay Tuned... More info at www.sendmail.com, see Integrated Mail Suite. </plug> Sorry, slow day at the office. I'm not in the habit of plugging our stuff but I know we'd be hearing about the "features" of an Exchange or Notes installation on the list later. Hate to see a site turn to the Dark Side...
