While implementing the message bounce in mod_smtpd I ran into a snag. I need to get mx records for host names!! There seems to be no portable DNS resolver library/interface. For UNIX there is at least res_search() and dn_expand() except on BSD this is in the standard library and in linux you need -lresolv.
I know there is apr_sockaddr_info_get but this doesn't handle getting mx records (or other DNS record types). Should a "resolver" API be added to APR. Actually I think yes and I think I'm going to implement this. Any objections? Rian
