Check your /etc/mail/sendmail.cf file for the following:

# who I send unqualified names to (null means deliver locally)
DR

# who I masquerade as (null for no masquerading) (see also $=M)
DM

If there are no entries here, it may be that the user you attempted to send to is not in the /etc/passwd file and it did not know where to send this to thus it gives an error. Since you are sending to your domain (someuser@my_company.com) and if those fields are blank, then it did not know where to send the email to. So it checks /etc/passwd for the username. If it's not there, it can then check /etc/mail/aliases for an alias for the user name

somuser: someuser@otherserver.my_company.com

If there isn't an alias, it won't send.

At some point there has to be a mail server that knows about all the users. My environment had an Exchange server so all email not specifically for the internet (someone@not_my_domain.com) or not specifically for a local user or aliases ( allunixadmins: joe, tom, charlie, scott) would go to the Exchange server. If your Sendmail server will be the main mail hub, then all users must be listed in /etc/passwd or have an alias set up in /etc/mail/aliases.

You need to check out the FAQ at Sendmail and/or read the Sendmail book to figure out how you want to move mail around. Once you figure that out, more specific help can be given.

mailstats

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

NAME

       mailstats - display mail statistics

SYNOPSIS

       mailstats [-c] [-o] [-p] [-P] [-C cffile] [-f stfile]

DESCRIPTION

       The mailstats utility displays the current mail statistics.

       First,  the  time  at which statistics started being kept is displayed, in the format specified by ctime(3).  Then, the statistics for each
       mailer are displayed on a single line, each with the following white space separated fields:

	      M 	  The mailer number.
	      msgsfr	  Number of messages from the mailer.
	      bytes_from  Kbytes from the mailer.
	      msgsto	  Number of messages to the mailer.
	      bytes_to	  Kbytes to the mailer.
	      msgsrej	  Number of messages rejected.
	      msgsdis	  Number of messages discarded.
	      msgsqur	  Number of messages quarantined.
	      Mailer	  The name of the mailer.

       After this display, a line totaling the values for all of the mailers is displayed (preceded with a ``T''),  separated  from  the  previous
       information by a line containing only equals (``='') characters.  Another line preceded with a ``C'' lists the number of TCP connections.

       The options are as follows:

       -C     Read the specified file instead of the default sendmail configuration file.

       -c     Try to use submit.cf instead of the default sendmail configuration file.

       -f     Read the specified statistics file instead of the statistics file specified in the sendmail configuration file.

       -P     Output information in program-readable mode without clearing statistics.

       -p     Output information in program-readable mode and clear statistics.

       -o     Don't display the name of the mailer in the output.

       The mailstats utility exits 0 on success, and >0 if an error occurs.

FILES

       /etc/mail/sendmail.cf	The default sendmail configuration file.
       /var/lib/sendmail/statistics
				The default sendmail statistics file.
       /etc/mail/statistics	The symbolic link to the statistics file.
