> You can always get it unlisted. How do you do that? The vast majority of blocklists I've interacted with have been unwilling to deal with questions, instead responding only that if you fix "something" (not always specified) automated measures will remove it from the list eventually. In my experience it has also been extremely difficult to deal with people using blocklists. It's easy to find a bunch of people using .tor.dan.me.uk rather than .torexit.dan.me.uk "just to be safe". Frankly, I'm not sure why the former list exists in the first place other than to be an arse? What threats do entry/relay nodes pose to you? |

Whenever one of our mailer IPs was blacklisted by one of the big targets (hotmail, gmail, etc) it would only be for 24hours after which I'd put it back into the pools (although, at least initially perhaps for our more reputable clients to warm it back up before letting the more dodgy stuff through it again). If you host your own NS's for the sender domains flipping SPF ips/ranges is not too hard (it's all automated for us, anyway).
The big boys work that way at least in my experience. I'm sure sometimes you'd hit a 'somedomain.foo' domain which is using a blocklist style thing that their (usually inexperienced) sysadmins think prevents them from receiving spam; but they're not worth arguing with. If you're doing email at volume shifting sends to another range for that client is usually 'enough' to get them through if they care that much about that one segment to ask you to do it.
If it's not then we'd usually refund instead of trying to negotiate with such admins.
Honestly though, blacklists have never been an issue for me and I've sent a ridiculous amount of email over the last 10 years...
