4.1.1:

  * SOAP server
  * Other webservers

5.3.4:
  * Check if we are allowed to mess programmatically wit /etc/* files
    (are they conffiles?)
  * Check if we ought to always use debconf notes instead of echoing
  * Support more webservers (like lighttpd)
  * Support alternatives to SUID binaries (like apache suexec)
  * Check if some dirs should also be (re)created, chown'ed and chmod'ed
    at daemon start time, in addition to package install time
  * Unify language resolving based on actual available l10n files
    (instead of current individual hardcoding both upstream in wizard
    and in debian/config)
  * Check each entry when adding to /etc/aliases and only warn if
    existing already to avoid duplicates (especially the generic
    "listmaster" might already exist).
  * Support alternative syslog daemons than sysklogd
  * Check if smrsh is needed (what is it?!?), and if its current
    location below /etc/mail is policy compliant
  * Check if l10n is better placed below /usr/share/locale
  * Favor exim4, or document reason for the uncommen sendmail dependency.
  * Symlink binaries to /usr/sbin (not /usr/bin), and check if they can
    maybe be installed there directly instead
  * Add src/README.postfix

6.0:
  * Check if we should pass --with-newaliases to configure, to ensure
    reliable build.
  * Consider passing postfix-specific options to configure - maybe
    shipped in branched postfix-optimized flavor-package
