Example postfix:

USERS=	postfix
GROUPS=	postfix maildrop mail

In ports/GIDs we need for full support
- mail:*:6:postfix
- postfix:*:125:
- maildrop:*:126:

The framework will then
- create the groups postfix and maildrop
- add postfix to the group mail

Without the predefined group mail the postfix can only use the framework
partially and do the rest (add postfix to group mail) with the pkg-install scrip





it is then not possible with the framework.
