Re: Best single-node setup

Hello,

my virtual server is 5 Eur/month running James 3.4 with Spring and 
Postgres. I reduced a little bit the requirements for the JVM because 
the amount of email to process is not that much.
The Spring configuration is verbose, not that easy, so I would like to 
try the Guice-JPA with Lucene as well one day, but keeping Postgres as 
backend.
