[Mimedefang] perl problem

[B. Tolka]

I my milter I have a mysql call below.   

$sth1 = $dbh->prepare("SELECT value FROM userpref WHERE username =
'$recip' && preference='whitelist_from'");


My slave is always getting killed because of an aprostophe in an email
address.   It fails at '$recip'.   

Is there another way to code the above line??


Thanks
