Operating Systems Solaris How do I configure sendmail to block all OUTGOING mail FROM one userid TO the world? Post 302403801 by jim mcnamara on Sunday 14th of March 2010 08:44:12 PM

You did block/stop/delete whatever caused the one account to become a spambot, right? Othwerise the problem will spread to other user accounts. And this answer becomnes pointless.

You can employ setfacl to block execute access for the sendmail image for use by one specific username. I would completely disable that account, and move it to the nobody group if you have one. I would also question any file that user had write acces to. Then give the user another, new account.

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.
	      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.
       /etc/mail/statistics	The default sendmail statistics file.
