Oracle Eloqua.com marketing emails

[David Jones <dj...@ena.com>]

Anyone have any experience with eloqua.com marketing emails and handle 
these with custom local rules?

Recently I have discovered questionable results for requests to 
unsubscribe from these emails.  The emails come from well-known domains 
using dedicated subdomains with this SPF record:

v=spf1 include:_netblocks.eloqua.com -all

Example envelope-from domains:
   marketing.verisign.com
   b2me.cisco.com
   engage.vmware.com

When the unsubscribe link is clicked, it takes you to a redirected page 
on eloqua.com with the senders logo and a message "You have been 
UNSUBSCRIBED from similar mailings."  If you click it a second time, 
there is no indication that you have already been unsubscribed giving 
zero confidence that the first request was honored.

I have unsubscribed some of my users and 2 weeks later they are still 
getting emails from the same envelope-from subdomain.

I am considering creating a local rule to block them using the AskDNS 
plugin based on the SPF record contents so I don't have to manually 
create blacklist_from entries for each one I find.

If they add IPs, then either,

  a) I never know because we don't get spam from them -- great.
  b) We get spam from them, and I track down and block the new IPs.

If they release some of their IPs on the market, whoever buys them will
have to complain (our postmaster address is in the rejection message).

You hard-coded the IPs based on their current SPF record?  What if 
things change and they start sending out different servers/IPs?  I was 
interested in a way to use AskDNS to lookup the SPF record and then 
match on the contents.  This could be useful for other senders in case I 
needed to subtract some points for specific SPF records without going 
all the way with a whitelist_auth entry.

We blocked some of their space back in 2013 with no complaints, and
thanks to their SPF record, just blocked a bunch more.
