Configure sendmail with SMTP

Hello,

I'm trying to configure sendmail with SMTP authentication on a SunOS 5.11 operating system. I have been read various documentation / tutorials and unfortunately is not working. I need help from someone who has configured smtp on this operating system.

When I try to send a mail, I have the following error:

Code:

The following addresses had permanent fatal errors -----
<username&test.com>

----- Transcript of session follows -----
550 5.1.2 <username&test.com>... Host unknown (Name server: mailhost.localhost.localhost.com: host not found)



--w5RL4kWQ029892.1530133486/localhost.localhost.com
Content-Type: message/delivery-status

Reporting-MTA: dns; localhost.localhost.com
Received-From-MTA: DNS; localhost

Remote-MTA: DNS; mailhost.localhost.localhost.com

--w5RL4kWQ029892.1530133486/localhost.localhost.com

I've looked into the sendmail configuration files to change host mailhost.localhost.localhost.com with my smtp server, but it does not exist.

In /etc/mail/sendmail.cf to the line

Code:

# "Smart" relay host (may be null)
DS

... where is DS we put the smtp server, I restarted the services and unfortunately the hostname does not change.

Thanks in advance.

sendmailconfig

SENDMAILCONFIG(8)					      System Manager's Manual						 SENDMAILCONFIG(8)

NAME

       sendmailconfig - configure sendmail for Debian systems

SYNOPSIS

       sendmailconfig [--no-reload]

DESCRIPTION

       sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems.

       In  the	simplest  case,  you  may  run	this program to (re)configure sendmail for your Debian system at any time. It will modify the file
       /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf.

       For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of  sendmailconfig  will
       preserve these changes provided they are made at the end of the file.

       Normally  sendmailconfig  will  ask  if	you want to reload sendmail after making changes to its configuration. The --no-reload option will
       avoid this question.

FILES

       /etc/mail/sendmail.mc
	      sendmail m4 input to generate sendmail.cf

       /etc/mail/sendmail.cf
	      actual sendmail configuration file

       /etc/mail/sendmail.cw
	      names for which we will accept mail in the standard configuration

       /etc/mail/sendmail.ct
	      names of trusted users in the standard configuration
