I just found these while going through my messages file... do I
have any need to be concerned???
(unicorn.it.wsu.edu is now in my /etc/hosts.deny...)

Mar 23 20:39:25 aries sendmail[7469]: setsender: "|/bin/mail
[email protected] < /etc/passwd": invalid or unparseable,
received from unicorn.it.wsu.edu [1

nrcpts=0, proto=SMTP, relay=uni

There were also attempts at connecting to my tftp port, although
at the time, in.tftpd wasn't on the system (it is now, and is also
in my hosts.deny to all except for local)

Thanks...
