A more accurate title would be -- CentOS 5.3 x86_64 Server and ISPConfig 3 Installation Tutorial (on 6 Pages)
And this is a very specific and slightly weird setup as well. Who uses mail quotas!? Well, I guess some people might but it's hardly common and unless you are setting up some kind of rural ISP or low budget community college or something why bother ..
Is it just me or are these howtoforge posts borderline spam?
I normally go look for a specific howto when I need one. There's no reason to clog my news feed with random howto's.
I've never used ISPconfig. How does it compare to Plesk or Webmin?
