sendmail on solaris problems

Hi everyone,

I have been given the task of getting sendmail going on a solaris box (2 days to be exact) and i am flying blind, i have never built sendmail before.

The sendmail will only need to send emails.. not recieve or anything.. its actually running on an application server which will then be sending notifications to users. but atm its trying to use the recipients SMTP server NOT THIS ONE!!

I have got things moving forward however Ive hit a wall... I have created the following mc file..

VERSIONID(`@(#)    1.5 (Sun) 09/12/01')
DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')
but when i run the command
root@jpapp1 # /usr/lib/sendmail -v </dev/null

i get this

Code: Connecting to 202.X.X.X. via esmtp...
220 Microsoft ESMTP MAIL Service, Version: 5.0.2195.6713 ready at  Wed, 21 Jul 2004 18:07:02 +0800
>>> EHLO jpapp1.
501 5.5.4 Invalid Address
>>> HELO jpapp1.
501 5.5.4 Invalid Address
>>> QUIT
221 2.0.0 Service closing transmission channel
/dead.letter... Saved message in /dead.letter
Closing connection to 202.X.X.X. is the email recipients address not MINE. so it is trying to send the email from the recipients emails smtp not the one on this server... any ideas??

Im really stuck

Sendmail has always been a nightmare to configure.

I've not tried it on solaris, but on HP-UX the configuration file is /etc/mail/


you will need to know some things before you start:
  • The fully qualified machine name of your SMTP server (MS Exchange server will work fine)
  • The fully qualified domain that your Solaris server is attached to
  • The top level domain name

If your SMTP server is
and your Solaris Server is
and your top level domain is

You should have the following lines (as a part) of your file


It would be a good idea to run: man sendmail

This will hopefully tell you were to find your configuration file.

You can send a test mail using mailx

mailx -s "Subject of test"

The main rule with sendmail has always been, if it works leave it alone.

Hope it all works out ok.

Forgot to say:

The command: mailx -s "test"

Works in the same way as telneting to the SMTP port (25) and performing a HELO command etcetera.

Therefore, you need to type in your email message at this point

To send the message put a fullstop on a line by itself and press return
