How can I find a file that contains a unique "Word" in AIX system?

[JoeZ]

Some AIX server in our system is sending a message "No new ns_web dead letters" to a user in our company. I think it may be 1 of four webServers of ours. I want to search through all files to find his last name(the unique word). What commands can I use?

what do the mail headers(in client)/logs (on pop3/imap/smtp) say???

Thanks for quick response. Which "Log" directory should I look in?

 

[gheist]

the one where events from mail.info goes from syslog

you may need to adjust /etc/syslog.conf and start syslogd on AIX if its out-of-the-box

ie

/var/msgs/maillog on AIX

/var/log/maillog on many other systems
