I used the Perfect Server How To to create my SuSE 11.1 server months ago. I installed ISPConfig, then uninstalled it, but the directory structure largely remains the same. The Apache server works fine. Postfix has worked fine until a few days ago, when I "cleaned up" the /srv/www/web3 directory a little bit. I may have broken Postfix. Postfix no longer starts. Mail.err reports "postfix/master: fatal: open lock file /var/lib/postfix/master.lock: cannot open file: Permission denied". Permissions shown below (I am only showing relevant data (to my knowledge): /var/lib # ls -l drwx------ 2 postfix root ... postfix /var/lib # cd postfix /var/lib/postfix # ls -l -rw------- 2 postfix root ... master.lock I have tried changing permissions to root, all, and back to postfix as originally found, to no avail. I have tried creating a new maste.lock file (w/ touch) to no avail. I am considering a Postfix uninstall/reinstall if I can't fix this issue. Any ideas or help would be appreciated, as the uninstall & reinstall may not be as simple as I need at this time.
