As I stated, no. I need the procmail filtering features.

I see, something like adding a hostName LDAP attribute to all my users in LDAP
dans putting this in dovecot-ldap.conf :

  pass_attrs=uid=user,userPassword=password,proxy,hostName=host

correct ?

I don't quite understand the proxy_maybe option :

proxy_maybe can be used to implement "automatic proxying". If the proxy
destination matches the current connection, the user gets logged in normally
instead of being proxied. If the same happens with proxy, the login fails with
"Proxying loops" error. This feature exists only in v1.1+.


Besides, let's say you want to split your load between 2 dovecot servers :
would you need a 3rd that would do only the proxying ?
