It increases the risk, but by how much? The wiki page doesn't give any indication of how many mails are stored in each file. Is is 5 mails per file or 5 files per mailbox? > The following is another cause for concern: > "This also means that you must not lose the dbox index files, they > can't be regenerated without data loss. " I was concerned about that but further reading indicates that these files hold only metadata. You may lose information on which mails have been read or flagged but the mails are still there. It also adds complication at the MDA level as procmail and friends can't simply save the mail in a directory. On the other hand, Dovecot is mature and well used software to these concerns have probably already been addressed somewhere. -- Neil Bothwick Blessed be the pessimist for he hath made backups.
