I see what you mean now...
The only way I can see to do this is with a file edit...
You'll need to edit the file includes/class_mail.php
Find the lines:
PHP Code:
if (isset($vbphrase['x_mailer']))
{
$mailfromname = construct_phrase($this->fetch_first_line($vbphrase['x_mailer']), $vbulletin->options['bbtitle']);
}
else
{
$mailfromname = $vbulletin->options['bbtitle'];
}
and change the 2 instances of $vbulletin->options['bbtitle'] to the hard coded name of your choice:
PHP Code:
if (isset($vbphrase['x_mailer']))
{
$mailfromname = construct_phrase($this->fetch_first_line($vbphrase['x_mailer']), "My Forum Name");
}
else
{
$mailfromname = "My Forum Name";
}
I didn't test this so backup the original file of course, but it should work.
