Operating Systems HP-UX Sendmail - relay Host unknown since adding dns Post 302949413 by MadeInGermany on Friday 10th of July 2015 11:35:28 AM
Old 07-10-2015
Code:
host 192.168.1.39

and
Code:
getent hosts 192.168.1.39

should give the same hostname.
getent (if available on your system) uses the libc defaults that is normally /etc/nsswitch.conf, eventually through a nscd cache.

For ipnodes (Solaris?) I recommend only "files". In few configurations "files dns" can make sense, but always "files" first, and "localhost" should be in /etc/hosts file.
(Not relevant here: also services should be "files" first, for performance reason.)
Do you have nscd with hosts caching (and ipnodes caching) enabled? (See /etc/nscd.conf and command nscd -g) Then restart nscd.
