As long as all you do is add to a mailbox. Deleting a message is still
heavy because it requires reading the entire mailbox and writing it
without the deleted message.
I use maildir for that reason as well as for backups. I keep 60 days
of offsite backups of my mail folders. Basically I create a hard
linked copy of yesterday's backup and then rsync today's mail. Every
day's backup is only a small fraction of the total first backup. That
saves both space and bandwidth.
