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.
