It does, in postinstall/passwd-grp.sh
In your case it looks like somebody ran "mkgroup -d" and overwrote /etc/group
instead of appending to it (or running "mkgroup -l -d").
No such mistake was made for /etc/passwd

This list would have even more traffic in that was the case...

How can we best insure that people know about and run XXX-config?
exim-config does check that the important groups/ids are present. It would
have detected your problem. There is little traffic about exim on this list
(well, this thread is an exception), partially because I add features to
exim-config as issues arise.

It's not used on other platforms, AFAIK.
As you have noticed in your 2nd try, exim won't run if a few conditions
are not satisfied. Verifying those is basically what exim-config does.
You don't even need that to send e-mail, at least if the postinstall ran OK.

The User control panel will also show the privileges (rights) that those
groups have.
You could also see what groups you are in by using "id", and then using
editrights to find the privileges of those groups. Not sure if it
can report that.
