What's the real difference between > $header .= 'From: info@villaarmonica.org.mx' .

See http://www.php.net/manual/en/language.types.string.php Under "Single quoted": .. escape sequences for special characters will not be expanded when they occur in single quoted strings. So you end up with a literal '\r\n' at the end of the line, not an actual carriage return & newline that you expect. -- Postgresql & php tutorials http://www.designmagick.com/
