Yes, this will still work.  However, since you have a .forward file, 
your LDAP email address will be entirely ignored.  This means that email 
to saper at toolserver.org will be delivered to your local account on 
hawthorn or clematis as well as being forwarded to your forwarding 
address.  

If you have no email address set in LDAP, then nothing will change from 
how it works at the moment, except that incoming mail from outside the 
Toolserver will arrive on clematis/hawthorn instead of on nightshade.

Not exactly. clematis and hawthorn will only handle incoming SMTP, i.e.  
mail to user at toolserver.org...

... which mean that if you send mail from a Toolserver system, it will 
be delivered by that system, whether it's delivered locally or forwarded 
elsewhere.  This includes mail from SGE and from cron, and it applies 
even if you send mail to an @toolserver.org address.  hawthorn/clematis 
are only special because they will be listed as the mail exchangers for 
toolserver.org.

Yes, as above.
