I prefer to run postfix rather than sendmail.. Scalix is based on the HP Openmail system. It's pretty much a complete replacement of the MTA. No postfix. I'm installing it for a small business. They use lookout for the client. This thing rocks. Shared calendar, public folders. All this stuff just works. I was able to integrate spamassassin and clamav with it also. The webmail access is really good too. They use tomcat5 for all the web stuff. All the administration is done via the java web interface. There is command line stuff I'm starting to scratch the surface on. I've installed community edition 9.4.2 and 10 on centos4. Good luck. Cheers, Tim
