mail_queue_enter: create file maildrop/XXXXXXXX : Permission denied

Hi, yesterday I messed up the ownership of a great part of my system, I fixed most part of it, but in the mail logs I see lines like

Apr 27 10:50:01 server postfix/postdrop[18698]: warning: mail_queue_enter: create file maildrop/522712.18698: Permission denied

permission looks ok
sudo ls -lad /var/spool/postfix/maildrop/
drwx-wx--- 2 postfix postdrop 4096 Apr 27 10:39 /var/spool/postfix/maildrop/

and sudo postfix check is also happy, so does anyone know what directory is meant by this error? I recieved some mails, so it might only affect a part of mails.

Thanks for your help

 

did you check the permissions for /var/spool/.... , too?

 

Yes and sudo postfix check, also check this. But in the mean time I resolved the issue by rebooting the server a process was apparently still running under the wrong user, and restarting postfix alone was not enough.

Thanks for your help
