[thelist] perl (help)

[thomas stephen]

hello,
 
i have a problem for my guest book.pl, if someone fill
a dumb e-mai identity such as "xxx" or "yyy" or any
thing expect e-mail format such as xxx at yy.net  , the
server crashes. Can any one provide a solution to
avoid anonimous logins even though he/she enters xxx
or yyy or anything on the space provided  for e-mail
entering.
 
stephen
