[SM-USERS] Error in "Unsafe Image Rules"?

[Greg W. <gr...@gr...>]

I just set up the 'unsafe image rules' plugin, and then got an e-mail from
a coworker that had an attachment.  Actually, I think it's just an HTML
message.  At any rate, the message was blank except for a link at the
bottom to either open or download the attachment, but when I clicked
'view' I got the following error:

Fatal error: Call to undefined function: addressbook_init() in
/Library/WebServer/Documents/squirrelmail-1.2.7/plugins/unsafe_image_rules/setup.php
on line 165

Any ideas about what might be wrong?  Maybe it's upset because I haven't
defined anything in the address book?  The error seems to indicate that
the function doesn't even exist, though.  I can always turn off the 'if in
addressbook' option in the plugin, but I don't understand why that plugin
is even relevant here...

I just checked the attachment, and it was indeed just the text of a
forwarded message.

Thanks for the help,
