Guess you're one of the lucky ones that has never had to fix b0rked mbox files. Consider yourself extremely lucky. It's not a lot of fun.

Again, you are one of the lucky ones. File your mailing list into the inbox, and try reading new messages while the system tries delivering messages. Pretty much guarantee you'll run into corruption. It's just the nature of the mbox beast. For a personal system, it's fine. For a heavily used, multi-user system, it's not so great. No matter how much we tried to train our users to use folders, most left everything in the inbox, which led to all kinds of problems. Even when it was a POP3 server. After losing that one last day to repairing a user's 100MB+ b0rked mbox file, we moved to Courier. We then moved to Cyrus for the performance. > The system we have serves hundreds of thousands of email accounts, and > millions of messages per day. > 2x sendmail boxes equipped with MailScanner, configured to forward to a > qmail NFS based backend with netapp mailstore, the pop/imap is the > extremely fast vpopmail/courier-imap, webmail servers are vpopmail > courier-imap with SM, and MySQL for SM calendars and addressbooks. > (Dont use SQL/LDAP for vpopmail/courier user authing, DJB's CDB format > is at least 6 times faster for lookups, (proven by many large > networks)) Good for you.
