ok, our 2 cents :)
We've installed and successfully operate several Sw-Soft Plesk installations, they run for more than a year already, and they have been extremely stable.
It is also nice to install a Greylisting server in front of a Plesk server. Then the amount of incoming spam is significantly reduced.
SW-Soft has also a very nice product called Virtuozzo, and you can build with it a system with quite low downtime in case of major OS or hardware failure.
Inside Plesk there's a custom-built qmail, spamassassin, DrWeb antivirus and the user database on the local MySQL server.
It's quite easy to integrate with other systems -- for example, our secondary DNS server creates the secondary zones automatically after they are activated on the Plesk server. It's also quite easy to create scripts for automatic import of bulky lists of email users. Also there's a Web/XML interface which could be used for integration with external systems.
Of course I'm talking of Plesk on Linux installations. There's also a version for Windows, but we never tried it (why should've we? ;-)
Although it's very well integrated and most of functions are done through the Web GUI, still it makes sence sometimes to do some plain old school Unix terminal work. It's just easier this way :)

We're looking around for a new mail server solution, since our mercur (www.atrium.de) server is just too unstable.
Preferably it should run on windows (we're just not at home on the *nix platforms), have all it's config options in a sql database, provide anti-spam and anti-virus out of the box, have a feature-rich webmail client and be tailored for a small ISP.
Our specs: ~700 Domains, ~4000 Users
