It seems the mail() function is stripping the trailing whitespace by putting a null character at the start of it, but this is somehow getting back into the PHP variable (as if it had been passed by reference?) so the PHP variable contains a null character where the trailing whitespace started before the mail() function was called. Reproduce code: --------------- <?php // to address with trailing space $to = 'tom@scl.co.uk '; // Output the ASCII code for the last char // in the $to address string print("Last char=".ord($to{strlen($to)-1})."\n"); // Send a message to the email address in $to mail($to, "Subject", "Message"); // Output the ASCII code for the last char // in the $to address string print("Last char=".ord($to{strlen($to)-1})."\n"); ?> Expected result: ---------------- Last char=32 Last char=32 Actual result: -------------- Last char=32 Last char=0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25923&edit=1
