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.
