Why not submit a fix to have getpwnam_r fixed instead? If a system library function returns an undefined error code, then that is a BUG. > Does postfix need to treat the EINVAL as if the user does not exist? > Is there a way to change the behavior of getpwnam*? EINVAL is not a documented result code. http://pubs.opengroup.org/onlinepubs/009695399/functions/getpwnam.html Postfix is built accoirding to standards, not by tinkering with library calls and guessing what the result means.
