Conclusion: On Linux, with file systems mounted with default mount option 'relatime', on an encrypted file system (encfs) mailx deviates from conventional rules of file times modifications. This will cause some applications (like mutt mail client) that rely on mbox's file times attributes to not work properly. Corinna, you have Red Hat's e-mail address, but I do not know if you are a dev or a user. We have an option to file Fedora Bugzilla bugs for procmail and mailx and let the package maintainers take care of it. What is your suggestion ?
