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.
