Hello, I have an admittedly basic question, but I have been trying to troubleshoot this for a while with no success.
I have enabled postscreen(8) on Postfix 3.1 and receive a warning in mail.log: “close database /var/spool/postfix/var/lib/postscreen_cache.db: No such file or directory (possible Berkeley DB bug)” A quick Google of this returns that this is caused on Debian systems that run Postfix in a jail (which matches my system). The most recent post regarding this appears to be here: https://tech.feedyourhead.at/content/postscreen_cache_db_no_such_file As per the blog posting, I stopped Postfix and created a directory in the jail for the postscreen_cache.db: $ sudo systemctl stop postfix.service $ sudo mkdir -p /var/spool/postfix/var/lib/postfix I moved the postscreen_cache.db file to this location: $ sudo mv /var/lib/postfix/postscreen_cache.db /var/spool/postfix/var/lib/postfix I set the permission and ownership on this file: $ sudo chown postfix:postfix /var/spool/postfix/var/lib/postfix/postscreen_cache.db $ sudo chmod 0660 /var/spool/postfix/var/lib/postfix/postscreen_cache.db I checked that the postfix user can access this file: $ sudo -u postfix namei -m /var/spool/postfix/var/lib/postfix/postscreen_cache.db I *DIFFER* from the blog in that I do not create a symbolic link - I use the Postfix main.cf configuration parameter below: postscreen_cache_map = btree:/var/spool/postfix/var/lib/postfix/postscreen_cache I then start Postfix: $ sudo systemctl start postfix.service When I check: /var/spool/postfix/var/lib/postfix I can see that postscreen_cache.db is updated as time progress, but I still get the warning about not being able to close the postscreen_cache.db database. What am I missing ? Thanks, - J
