Be a nicer citizen with respect to mailbox locking. Perhaps prune/shorten IMAP mailbox URLs in messages? They may be quite long and may contain the sensitive password. Perhaps find a clean, lean replacement for all that clutter in the IMAP urls. Require --output-dir for IMAP archiving? Otherwise we just drop the archive in in the current working directory. Switch to fcntl(2) locking? That would be NFS-safe. Perhaps make the locking method configurable? Check all items below, which are from the original author. :-) .archivemailrc support Specify an option to not seteuid() when run as root? When you get a file-not-found in the 6th mailbox of 10, it aborts the whole run. Better to fail gracefully and keep going. Think about the best way to specify the names of archives created with possibly an --archive-name option. Add more tests (see top of test_archivemail.py) We need some better checking to see if we are really looking at a valid mbox-format mailbox. Lock any original .gz files - is this necessary? Check for symlink attacks for tempfiles (although we don't use /var/tmp) Add an option to not cut threads. Add MMDF mailbox support Add Babyl mailbox support Add option to archive depending on mailbox size threshold - is this a good idea? Add option to archive depending on number of messages - is this a good idea?
