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

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.

local.users(4)						     Kernel Interfaces Manual						    local.users(4)

NAME
local.users - Specifies mail recipients on the local host. DESCRIPTION
The local.users file contains a list of user names whose mail is to be delivered to the local host and whose return address is user- name@hostname. Entries in the local.hosts file are in addition to other local users (such as root and postmaster). See sendmail.cf(4) for a description of other local users. You can add entries to this file if the host is configured as a simple client and either of the following is true: The user wants their mail delivered on this machine rather than being forwarded to the mail server. You are adding aliases to the /var/adm/sendmail/aliases file. When the host is configured as a simple client, the alias must be added to this file and the aliases file. A simple client is defined as a host that had the mail system configured using the MailConfig application from the System Management utili- ties or configured using the mailsetup utility's Quick Setup menu. The format of the file is as follows: User names are separated by blanks or new lines. Multiple user name can be specified on a line. Blank lines are ignored. A comment mark (#) ends the line. After modifying the local.users file, you must restart the sendmail daemon to apply the changes. Use the following command: # /sbin/init.d/sendmail restart EXAMPLES
root postmaster rw # A comment followed by an ignored blank line. # Another comment. mariah # Another comment. carey # Leading blanks are acceptable. FILES
Specifies the path name for the file. RELATED INFORMATION
Files: sendmail.cf(4). delim off local.users(4)
