If I had lets say 10 nodes handling incoming SMTP and delivery to local
maildirs in parallel and independantly on a network storage and imapping this
from another independant 4 nodes, then building a not needed bottleneck by
shifting over the local delivery via director and LMTP to fewer nodes is just
braindead creation of high loads on few boxes.

And btw it scales perfectly because all that is needed if load increases is
up'ing additional nodes for SMTP/delivery or IMAP _which are all the same (of
two types)_.

The loadbalancer needed for this can be equally used for e.g. web, ftp and
other services. So there is absolutely no extra stuff needed for the mail
setup.
