qmail-remote smtp auth with qmail-ldap

I'm not sure this place is till alive, but let's try...been a long time 
since I've tracked this mailing list.

Anyhow, I'm stuck in a situation where my ISP is blocking outgoing port 
25, and I need my daily logs etc to go somewhere - something like gmail, 
since my primary address is there.
But, Gmail wants TLS with AUTH PLAIN authentication, and, though I can 
set smtproute for everything, I can't login to Google's smtp servers.

I've seen a bunch of remote smtp auth patches for regular qmail, but 
none for qmail-ldap. Even, somebody said it won't be done because qmail 
is supposed to talk to others directly on port 25...obviuosly, a lot of 
time has passed since then, and it is obvious that some thing need to be 
updated in qmail-ldap patch.

So, does somebody know of a way to make qmail-ldap (qmail-remote to be 
precise) work with smtproutes that has username and password in it for 
remote auth?
Perfect solution would be to have different settings for different 
remote domains...
