Moreover, I don't think that reloading the system is useful in any case. AFAIK, the resolv.conf file is not used directly by postfix itself, but by the C library, which does not cache its contents, since it may change at any time and many running programs (not just daemons) use it via the C library. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
