For the attribute postalAddress new lines are supposed to be represented
as "$" characters in the stored data.  And mapped to "\n" when read by
the application, and "\n" turned back into "$" when updated.  I've been
meaning to look into this but unfortunately haven't had the time.  If
you could patch for that behaviour as well it would be much appreciated 
(at least by me).

See http://ldap.akbkhome.com/attribute/homePostalAddress.html 

The syntax 1.3.6.1.4.1.1466.115.121.1.41 for these address attributes is
"postal-address = dstring *( "$" dstring )".

I think Turba should implement the standard.  Tracking evolution for
"correct" behaviour is a mistake (IMHO) as the LDAP support in evo is
really really bad.  They will eventually fix evo.
