MyBB uses nl2br function to convert new lines to <br />. For example in inc/taks/massmail.php there is:
if(strpos($mass_email['htmlmessage'], '<br />') === false && strpos($mass_email['htmlmessage'], '<br>') === false)
{
$mass_email['htmlmessage'] = nl2br($mass_email['htmlmessage']);
}
I don't really understand the purpose of this code but I guess if you add <br /> somewhere to your mass mail, the new lines aren't converted.
