note 19373 modified in function.mail by derick

Watch out for subject lines with a \n at the end (or presumably anywhere). mail() won't strip this off the end and any additional headers specified in the fourth parameter will get stuck at the beginning of the body. Exmaple: mail("joe@example.com", "Registration Confirmation\n", "This is to confirm your registration... blah...", "From: registration@example.com"); Sends a message to joe@example.com with a subject of "Registration Confirmation" as expected, but shows the userid of the process running the web server as the sender and has the following as a body: --------------------------------- From: registration@example.com This is to confirm your registration...blah... --------------------------------- a quick "trim($subject)" solves this. --was-- Watch out for subject lines with a \n at the end (or presumably anywhere). mail() won't strip this off the end and any additional headers specified in the fourth parameter will get stuck at the beginning of the body.
