The Spammers try to send e-mail beginning with aaaa@domain.com to zzz@domain.com generating a lot of mail of error messages. I want to disable user unknow error message.

Check out my annotated sendmail.mc file, from which sendmail.cf is built. Its at http://www.experts-exchange.com/Networking/Email_Groupware/Sendmail/Q_21116293.html

Specifically, you are probably interested in the following settings:

define(`confDOUBLE_BOUNCE_ADDRESS', `xxxxxxxxx')dnl
define(`confDEAD_LETTER_DROP', `/some/path/here')dnl
define(`confMAX_RCPTS_PER_MESSAGE', `###')dnl
define(`confBAD_RCPT_THROTTLE', `#')dnl

As detailed in that Question. A number of other anti-SPAM settings are included, but those are the ones that most-directly relate to your issue.

Hopefully, you have a modern version of sendmail (v8.12.x or better). If you don't, then you need to upgrade. http://www.sendmail.org
