rblsmtpd 451 Sender has sent to LashBack

Bounce message received:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]

Malformed SMTP reply from mail.server.com [192168.1.1]
in response to initial connection:
rblsmtpd: 192.168.6.62 pid 14483: 451 Sender has sent to LashBack
Unsubscribe Probe accounts:
retry timeout exceeded

Looking further into this it appears that the sending IP address was listed in a RBL black list.  The RBL server being queried was: ubl.unsubscore.com

This in turn (www.unsubscore.com) took me to: http://www.lashback.com/support/UnsubscribeBlacklistSupport.aspx

Most RBL systems return a useful message with a URL, but, not lashback.

Cacti error on Plesk Ubuntu 6.06 server

OS: Ubuntu 6.06
Cacti 0.8.7e
Plesk 9

Setting up cacti went fine until trying to run the poller:

# sudo -u cacti /opt/psa/bin/php-cli /var/www/vhosts/hostname/httpdocs/poller.php
sh: /php-cli: No such file or directory
sh: /php-cli: No such file or directory
sh: /rrdtool: No such file or directory

Had to modify the php.ini (/etc/php5/cli/php.ini) for the php-cli binary:

;safe_mode = On
safe_mode = Off

The cacti poller did not like safe mode being enabled on CLI PHP binary.  After this was changed, cacti started polling properly.
