Right, I looked at the code wrong. I think I won't change this in v1.x
because it might break something, but you could move

	ret = chdir(full_home_dir);

in src/master/mail-process.c just before:

	client_process_exec(set->mail_executable, title);

and then it should work with mail_drop_priv_before_exec=yes. I'll get
this fixed properly in v2.0.
