I've got a new box that was built using The Perfect Server - Ubuntu Gutsy Gibbon (Ubuntu 7.10) tutorial. It has ISPconfig and Webmin installed (each has features the other lacks). Everything seems to be working except that I can't seem to get any users logged into email from Thunderbird or Eudora. The error message that keeps coming up is ERR chdir Maildir failed. Users can FTP into their home directory as web8_username successfully. (where 8 is a client with several users) I can use Webmin's "read user mail" and verify that mail content is coming into the server and that there is valid mail to download. I can send user mail from Eudora and it arrives at the destination successfully, so SMTP is configured correctly. I tried maildirmake and it says everything is already configured. The .config stuff is in the /var/www/web8/user/web8_username folder The actual mail is in the /var/mail/web8_username file. So where is Postfix looking? and How can I fix it?
