thanks bjorn - this is very helpful.
i assume from that config extract that we can take the granularity even
further & have for example:

        # this contact is labeled "mailDBAs"
        contact.mailDBAs.command mail -s "Bad things!" dbas@xxxxxxxxxxx
        # this contact is labeled "mailWEBteam"
        contact.mailWEBteam.command mail -s "Bad things!"
        web@xxxxxxxxxxx
        
        & then configure specific nodes or even service contacts (eg.
        'df.contacts mailWEBteam') to go to different mailboxes?
        

thanks again for your reply.

martin.
