Hello all, I recently followed the "The Perfect Server - Ubuntu 10.04 [ISPConfig 3]" to set up a server. Everything went well, just for one thing : postscript doesn't read the mysql database of users, and just uses normal unix users. Courier does sees the database, and lets users login with it. To put it simple: the mail server works, but it just doesn't use the virtual users. Anyone have an idea what the problem could be? main.cf : http://pastebin.com/rP2ZrAjm Thanks!
