Operating Systems Solaris Mailx , sendmail and mailhost Post 302966863 by javanoob on Wednesday 17th of February 2016 10:20:04 AM

Smiliehi all,

sorry for bring up this thread.
I happen to encounter this setup below

Code:
 
 disabled       Jan_23   svc:/network/sendmail-client:default
online         Jan_23   svc:/network/smtp:sendmail

 ps -ef | grep sendmail
    root  2838  2101   0   Jan 23 ?           0:49 /usr/lib/sendmail -bl -q15m
  oracle 25537  9002   0 20:42:07 pts/2       0:00 grep sendmail

There is also no mailhost set in the /etc/hosts nor DNS (using nslookup) and yet I can still send out email using mailx from that server.

There is a local sendmail daemon listening at port 25 though.


Does it means

1) when sendmail-client service is disabled, it just means that there will be no daemon to push the mclientqueue but mailx will still spawn a sendmail process as a msp and read the submit.cf

2) having no mailhost define in /etc/hosts and dns, and a sendmail daemon (MTA) listening at local port 25, can I say that the local sendmail MTA directly
resolve the next hop to the actual mailserver of the recipient / sending out without going through a relay ?

Regards,
NoobSmilieSmilieSmilie

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)
