@JDM71488Oct 04.2006 — it looks just like a user-defined variable that is later checked in an if statement. where did you see this?

@RiannaauthorOct 04.2006 — Thanks, its in this, but don't know what it means.

$headersep = (!isset( $uself ) || ($uself == 0)) ? "rn" : "n" ;

@NogDogOct 05.2006 — To the best of my (imperfect) knowledge, the header separator should always be "rn". That will be the default setting from that expression unless $uself is set somewhere earlier in the code with a value that is not 0, empty, nor FALSE.

i believe is the same thing as
[code=php]if( (isset($useIf) == false) || ($useIf == 0) )
{
$headersep = "rn";
}
else
{
$headersep = "n";
}[/code]

@felgallOct 05.2006 — Depending on which email program is running on your server the headers need to be separated either by rn or just n. If you have the wrong separator between headers then the email will not send properly. That parameter in the code is obviously there to allow those using Qmail and other programs that require n instead of rn to be able to pass a value to the page to get it to change the header separator.

Just curious: is this a case where the program (e.g.: Qmail) is automatically (and perhpas sloppily?) converting "n" to "rn" regardless as to whether it already has a "r" preceding it, so you'd end up with "rrn"?

Success!
