Having recently migrated all the stuff on *.trailing-edge.com to a 2010 era server (as opposed to the 2000 era server it was on - previous to that it had been on an Alpha with VMS, and previous to that it had been on a VAX with VMS) with fresh installs of all the software I was pleasantly surprised with the advances that have been made in apache and mailman configuration over time especially with respect to virtual domains etc. In particular the Ubuntu distribution was very straightforward to deal with... after I had adopted to the more modern configuration techniques. And spamassassin can be better integrated with postfix and mailman than in the past, to the point where the obvious spams never have to make it to a moderator's mailbox or turn up as a bogus request to the admin address. I'm not sure you need to stage through an intermediate platform, BTW. Just bite the bullet and go to the final platform. Unless you really enjoy installing and configuring everything twice. Although I was pleasantly surprised with the new Apache etc. configuration methods I still wouldn't want to do it twice. Tim.
