Postfix Admin

I just ran into this "feature" as well. In 2.3 if the user sets up forwards
from his postfixadmin user interface, the super/domain admin 1) doesn't see
them and thus 2) can't change them. In my opinion point 2) here is also
important, as the domain admins should be able to fix things the users have
screwed up. Good to know a fix is coming.

Done in SVN r751.

Needs $CONF['special_alias_control'] = 'YES' (which results in an
additional "To" column in the mailbox list), but I'm not yet sure if this
is the right config option to check against.

Reverted most changes from r572 in r652, therefore the previous comment is
obsolete.

BTW: $CONF['show_popimap'] = 'YES' shows a flag on all mailboxes with
aliases pointing to the mailbox - maybe this check should be inverted to
highlight mailboxes that don't receive mail because of a changed alias.

Current status: (tested as superadmin, svn r650)
- default mailbox aliases (just pointing to the mailbox) are not shown (as
expected)
- non-default mailbox aliases (for example pointing to mailbox + external
address) are shown in the "Aliases" list - independent of
$CONF[alias_control/alias_control_admin/special_alias_control]. That's not
what I would call "expected behaviour"...

This problem was introduced in r572 (not the first one with the patch from
https://sourceforge.net/tracker/index.php?func=detail&aid=2567466&group_id=191583&atid=937966
) - seems I'll have to (re)read this patch carefully if it brings more side
effects...
