[Dovecot] Plugin to handle message saved and handle move from tmp to cur/new

Hello everyone....

I need to finish my plugin, but i depends from some stuffs in the save/move process that i can't find how its work.

In new zlib plugin (2.0) , the message is saved compressed now, but i dont find how is done the process to write the file to tmp, and move it to the cur or new directory (inside .Sent).

I need to hook this function, to get access to some variables, like Flags and filename.

There is a way to do this ?

Tks.
