Hi Experts,
I have one mail account ( old employee) who is receiving alot of spams. Actually, I want to get rid of this account but couldn't find  this username in /etc/passwd  and even tried some other locations like /var/spool/mail etc .
How can I find this ( probably hidden) mail account and delete this account from our mail server( Red Hat Linux 7.2.4)? Also, any effective method of blocking spams on our mail server.

Unless the system is set up to use the Cyrus IMAP or Courier IMAP server only those accounts listed in /etc/passwd or in the aliases/virtusertable maps can receive mail. If the system has Cyrus installed it might be set up to use "Cyrus only" auth info via sasldb and there'd be an /etc/imapd.conf that would define that auth method and the location of the mailstore.

If these messages are showing up in other folk's mail you are probably being confused by the To:/From: headers in the message. That's not used for mail delivery and corresponds exactly to what's on the piece of paper inside of an envelope that the Postal service can't see. There's a different set of envelope headers that are actually used for mail delivery and that are stripped off during delivery.

A good anti-spam/anti-virus/email-protection system is MailScanner (see http://mailscanner.info).
