But in my case it was sendmail that complained it didn't find the onw host. I forgot the details, but i think the /etc/hosts part of the resolver library is broken with this. Ah, yes, i remember: sendmail apparently tries to lookup "${hostname}.", i.e. it calls gethostname(2), and appends a dot to force DNS to not use the search order. The /etc/hosts part of the resolver library cannot handle this unless the host is listed with the trailing dot in /etc/hosts. I think this is a bug, and this part of the resolver library should just remove a trailing dot, to be (bug-)compatible to the DNS part. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
