One of our Linux cPanel servers have been blacklisted by Yahoo. I followed their recommended.
I see a lot of these errors in /var/log/exim_mainlog:
So, following the suggestions here: What are some best practices when sending to Yahoo! Mail? | Yahoo! Postmaster Help
I can safely say that, from a hosting side:
Many of the other options on that list is the responsibility of our clients, and I honestly don't know how to check and see if all clients follow those practices w.r.t. mailing lists (i.e. using opt-in / opt-out, pay attention to email content, etc).
So, does anyone know how we can clear the Yahoo blacklist, and keep a better tab on clients? It's a shared server, so it's a bit tricky to know if / when a client sets up a mailing list, and if they do follow the correct procedures.
Any pointers or help with this would be appreciated.
I have spoked to Yahoo about this a few times but always just get their crappy canned response telling me to follow the recommended guidelines, but then nothing more from them.

So, following the suggestions here: What are some best practices when sending to Yahoo! Mail? | Yahoo! Postmaster Help
I can safely say that, from a hosting side:
- We don't use DKIM, since cPanel doesn't officially support it, but we have SPF & DomainKeys installed on all domains.
- PTR records for the server is setup properly.
- The mail server is secure, and not an open relay
Many of the other options on that list is the responsibility of our clients, and I honestly don't know how to check and see if all clients follow those practices w.r.t. mailing lists (i.e. using opt-in / opt-out, pay attention to email content, etc).
So, does anyone know how we can clear the Yahoo blacklist, and keep a better tab on clients? It's a shared server, so it's a bit tricky to know if / when a client sets up a mailing list, and if they do follow the correct procedures.
Any pointers or help with this would be appreciated.
I have spoked to Yahoo about this a few times but always just get their crappy canned response telling me to follow the recommended guidelines, but then nothing more from them.
