[Systems] Removing a Random Block List

Hi Sysadmins,

It is a pain to run a main server these day because of RBLs.  So, many 
people prefer to use managed services like Mailgun to send their emails 
for SaaS apps.  I run a saas app these days, called Presenter Club [1] 
(which is aGPLv3 licensed btw), and I use Mailgun.

Anyway, many of my own emails were being permanently dropped by 
sunjammer.  Turns out that Mailgun is on a RBL [2].  I think that 
Mailgun (and their parent Rackspace) is probably doing good things to 
protect ip reputation, so any block list that blocks them is probably a 
piece of shit.  Mailgun is a big service, so I don't want other sl 
members to be loosing mail messages.

I've removed the "reject_rbl_client bl.spamcop.net" line from our 
postfix configuration.  I hope that that is OK with you all.
