Note: I don't understand how to use this at all!!

* Parallel provides v.s. Requirement
  - Well, generally I don't know how other people try to
    resolve this.

    Main package requires one "-database-driver" package
    and there are 3 package which provides this package
    (BTW "dbmail-database-driver-driver" on -mysql package
     is a typo, isn't it?). Then:

-------------------------------------------------------
    i.e. "yum install dbmail" always try to install
    "dbmail-mysql" because on using yum the shorter name
    package, and the alphabetically prior package (if name
    length is same) wins yum game.

   Well, for people who want to use postgresql-based dbmail, he/she
   can do this by explicitly directing -pgsql package, i.e.

-----------------------------------------------------------
    Anyway main package requires -pgsql or -mysql or -sqlite package and I think
    this must explicitly selected by the sysadmin who want to use this.

    So:
    I think it is better that 
    * -pgsql or -mysql or -sqlite package does not provide -database-driver package
    * main package does not require -database-driver package
      If do so, "yum install dbmail" only installs dbmail package
    * You write "README.fedora" which explains that to use dbmail on Fedora
      sysadmin has to install -pgsql or -mysql or -sqlite package by himself
according
      to what database he wants to use. I think this is no problem
      because dbmail cannot be used only by just installing your
      binary rpms and needs some settings anyway.

   For two packages I reviewed, this situation occurred, and in both cases
   submitters added README.fedora to explain this.

* Permission
-------------------------------------------
E: dbmail non-readable /etc/dbmail.conf 0660
-------------------------------------------
   - Just explain why 
     * others should not able to read this file
     * and group should have write permission

* Documentation
  - README.solaris should perhaps be removed (because we are not on solaris).
