/export/mailboxes/j/o/h/n/johndoe.mboxIn the past I've actually found that reversing the letters gives much better randomosity around the directory structure so, johndoe () clown org would end up in e/o/d/n/johndoe and you don't take much of a hit for this.
i'm currently implementing a largish mail server, and have come up with what i think is a nice way to deal with scale and redundancy, etc, etc. what i have done is create a couple DNS zones, which are like: $ORIGIN mailbox.domain.com bob IN CNAME popserver1 john IN CNAME popserver1 bill IN CNAME popserver2 $ORIGIN smtp.domain.com bob IN A 10.1.1.1 ; ipaddr of mailserver1 john IN A 10.1.1.1 ; ipaddr of mailserver1 bill IN A 10.1.1.2 ; ipaddr of mailserver2 then, users are told to set their SMTP to username.smtp.domain.com and to direct their POP/IMAP client at username.mailbox.domain.com. you might even be able to get away with a single map. incoming mail should direct username () domain com to username () username domain com in any case, using this method, you can now arbitrarily store mailboxes on any of several machines, even possibly in several locations. if a server fails, you can quickly redirect the users to another server so that new mail piles up in their new mailbox, and you can restore the broken server on a more leisurely pace. this can be extended to allow users to check their email with a web-based packet at http://username.mailbox.domain.com, or even be shortened so that they can have personal website http://username.domain.com how to implement the actual DNS is left as an exercise of the student. -- [ Jim Mercer jim () pneumonoultramicroscopicsilicovolcanoconiosis ca ] [ Reptilian Research -- Longer Life through Colder Blood ] [ aka jim () reptiles org +1 416 410-5633 ]
