Advanced Guestbook Notification not working

I am getting the mail send error in my mailerror.log file "From address not in member domain. Message not sent" What email from address does Advanced Guestbook use for new guest book entry notification, and is it possible to change it easily. I have tried looking though the code for it, but have not found it. From what I understand my ISP requires the send from email address to be from my domain.

Thanks in advance.

When a Comment is added to the guestbook the Comment is listed with a black font color. Is there are easy way to change it? I tried all the font color settings in the admin function to no avail.

I know this is an old post but in case anyone comes by in future with the same problem.

I'm guessing the site is hosted by Yahoo! Seems to be some sort of php conflict resulting from anti-spam policy. Had exactly the same problem, made the following changes and it all works fine...

Open the file add.class.php in the lib sub-directory, find the following (should be line 266)...

$from_email = ($this->email == "") ? "nobody@$host" : $this->email;

replace nobody@$host with your own (valid) e-mail address.

Save it. Test it & it should work. If not then

Have fun!

I'm one other yahoo user.
Thank you.
