[Dbmail] Stopping imapd, pop3d

[Peter Darley]

Folks,
        I have been scouring the DBMail man pages, and online stuff, and I can't
find a gracefull way to stop dbmail-imapd or dbmail-pop3d.  Is the standard
to just do a kill -9 of it? and if so, can I just send this to a single
process (and if so how do I know which one) or do I need to send it to each
child?
Thanks,
Peter Darley
