Hi everyone at HowToForge, this is my first post here. I'd like to use ISPConfig 3 with Dovecot (preferrably v2.x) and do IMAP/POP3/submission traffic accounting. Preferrably on CentOS 6, but Ubuntu 12.04 LTS or Debian 6 would also work. According to a recent forum post by Till this should be possible with ISPConfig 18.104.22.168. I'd like to give this a try and set this up in a VM tomorrow. Before I do, is there something I should be aware of in this context? Are there any known issues with this setup? Should I prefer Debian 6 over Ubuntu 12.04? I will probably use this how-to unless you recommend otherwise. And most importantly, should I expect traffic accounting to work out of the box, or will I need to make any manual changes to make it work? Thanks in advance!
