But it has to work on machines even without IPv6... like Solaris7

What about...

IF [x] {event[, event]...} ...

or does this involve an in additional token between x and event?  So it is
compatible with our current syntax.

Instead we can simplay add a token to the alert statement, to have the
requested functionality, e.g.:

alert [once] emailaddr.

And we should have a global "set alert" statement too.  These are added to
all services... All my 80 services do have the same alert statement...
would save space.
