} It seems that the $Sender variable not always has the '<' and '>'
} caracters, like in: <user at domain>
} Sometimes it get just: user at domain

     $Sender is exactly what the client sent as the parameter to "MAIL
FROM:"

} I wanted to ask if this is ok?

     Technically, it is a syntax error; but, sendmail generally accepts
it, so you must be prepared to handle it.
