I forgot to say that i really put some effort into the manual (and it will be even better in v14.9). So the answer for this can also be found in there – the entry for the `file' command reads: MBOX files (flat file-based mailboxes) are generally locked dur‐ ing file operations in order to avoid inconsistencies against concurrent modifications. Mailbox files which S-nail treats as system mailboxes will also be protected by so-called dotlock files, the traditional way of mail spool file locking: for any file ‘a’ a lock file ‘a.lock’ will be created for the duration of the synchronization — as necessary a privilege-separated dot‐ lock child process will be used to accommodate for necessary privilege adjustments in order to create the dotlock file in the same directory and with the same user and group identities as the file of interest. Also see mbox-rfc4155[356] for fine-tun‐ ing the handling of MBOX files. Ciao! --steffen
