I don't know about your other two questions, but :)

I used to use LDA, but little issues crop up with it, mainly doing  
with upgrades and interfacing to it from the mda. Generally these are  
one time setup issues (except when upgrades undo changes). For the  
upgrade issue I finally switched to LMTP, and I love it, the logs it  
produces are much nicer, I don't have to worry about upgrade or  
anything else having compatability issues, cause it's just a  
connection, no direct program interfacing going on.

The paramaters that get passed, while not that hard, can be  
interesting to setup, it seems lmtp passes much more info than you  
could pass to the deliver-lda program on the command line.
