I installed postfix freshly as satellite system. I need to authenticate on my mail providers smpt. There postfix needs to build a sasl database from my sasl-passwd file. But it fails to do just that. How do I fix this error (last line)?:

root@confus:/etc/postfix# echo 'smtp_sasl_auth_enable = yes' >> main.cf
root@confus:/etc/postfix# echo 'smtp_sasl_security_options = noplaintext noanonymous' >> main.cf
root@confus:/etc/postfix# echo 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd' >> main.cf
root@confus:/etc/postfix# ll
total 116

root@confus:/etc/postfix# postmap hash:sasl_passwd

inb4 'sudo': Notice the "root@confus"

"You need to make sure that postfix user is able to read that file. You can post the output of sudo ls -l /etc/postfix/sasl_passwd.db to get more help."

And from the comments: "Change the owner of the config directory of postfix to postfix and it works."

  • Indeed it does. But wow, that's just babytown frolics. Why are the permissions not set in the first place? – con-f-use Jun 3 '11 at 12:36

Usually, this fixes this problem

   cd /etc/postfix
   sudo chown -R postfix .
   sudo chgrp -R postfix .
   sudo chmod -R ugo+rwx .

Its important to also make the postfix directory writeable by the postfix user as it sometimes tries to create or replace files here (which it should probably keep somewhere else!)

  • Made my problem worse. In addition to the "No such file or directory" error, I'm also getting: postmap: warning: /etc/postfix/dynamicmaps.cf: file is owned or writable by non-root users -- skipping this file – TerranRich Apr 27 '18 at 19:20

Same for me, problem is worse after this

Linux ... 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u2 (2019-05-13) x86_64 GNU/Linux

to turn back:

chown root:root dynamicmaps.cf
chmod 644 dynamicmaps.cf

After trying again postmap sasl_passwd, sasl_passwd.db is created and looks OK
