[SURBL-Discuss] Capital One redirector

I'm not so sure - I suspect they may do nothing, and RBL will go unused.

How will the maintainers of this new RBL deal with either of these 

A - Mail admins start using the redir-SURBL or whatever they're calling 
it, and everyone complains that mail from these sites isn't working, and 
the admins are pressured into disabling the feature.  This will decrease 
its the RBLs popularity, and there's no pressure on those listed to work 
to get off the list, since no one's using it.

B - Because big organizations are listed, no one adopts it because they 
know it will be a nightmare to deal with complaints.  There is no pressure 
to get off an un-used RBL, so no one changes the bad behaviour.

Maybe I'm missing something, but since these domains are included in SO 
MANY ham emails, there's no chance I'd think of enabling this in my 

Perhaps the redirect-SURBL (or whatever it's called..) could look at the 
full URL, not just the FQDN.  Really you don't want to block dell.com, you 
want to block dell.com/some-insecure-redir/foo.php etc.

I hope this didn't all sound negative but to make this effort worthwhile 
someone has to figure it out.

RE: [SURBL-Discuss] Capital One redirector

It'll be interesting when Microsoft, Google, Dell, and other huge sites
are listed in that gray list.
