prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  We need to check the (persistent) postfix mailqueue permissions
  As the postfix and postdrop uid/gid might change (especially with a change of base image), it is needed to check the directory permissions on /queue before starting postfix
  
  --- END ISSUE ---
