    | Because all data could be in all maps. What you want would probably an

    I have no plans to add an LDAP server, nor an SQL server.

    How will I transfer the file to the new machine? I want it to be a
    separate file for a different domain

    Is there a Postfix man page that lists all the other Postfix man pages?

    Your experience and my experience aren't the same, apparently. Now I've
    only been using it for half a year, but it has been rock solid reliable
    and I have not lost a single thing. I have lost data occaisionally with
    ext2.
