Email address validation, is there a way to use Regex or other fuzzy searching?

Question

I would like to use PL/SQL for Email address validation, is there a way to use Regex (regular expressions) or some other fuzzy searching for that? Using % and _ wildcards only take you so far...
I need something that will verify alphanumeric charectors (no ",'.:#@&*^ etc.) any ideas?
Current code:
if email not like '_%@_%.__%' or email like '%@%@%' or email like '% %' or email like '%"%' or email like '%''%' or email like '%
%' then
The last line is to make sure there are no linebreaks in the middle of the email address, is there a better way to signify a line break, like \n or an ascii equivilent?

Michael:
The as noted in the previous post, DBI is a Perl package that allows Perl to talk to various databases, including Oracle. We use DBI on several UNIX servers, and it does not require ODBC, and I have always found it to be extremely quick. Things may be different in the Windows world.
If you are spooling files out to run through Perl anyway, you may want to take a look at DBI. You could probably modify your existing scripts to use DBI fairly easily. The basic structure using DBI is like:
use DBI;
my dbh;       # A database handle
my sth;       # A statment handle
my sqlstr;    # SQL statement
my db_vars;   # Variables for your db columns
# Connect to the database
$dbh = DBI->connect( "dbi:Oracle:service_name","user/password");
$sqlstr = 'SELECT * FROM emp WHERE id = ?' # even takes bind variables
#Prepare statement
$sth = $dbh->prepare($sqlstr);
$sth->execute(12345);  # Execute with values for bind if desired
# Walk the "cursor"
while (($db_vars) = $sth->fetchrow_array()) {
