"If you have an active site, it is important to consider that some ISPs may decide to block your forum's emails simply based on the volume of emails when you use a plugin like this. Make sure your website has proper SPF, Sender ID and DomainKeys to help delay blocking but if it's a very large site you'll probably have to pay a whitelisting service to stop blocks eventually."
Hi _ck_,
Thanks for this plugin. Can you please suggest how we go about setting proper SPF, Sender ID and DomainKeys?
Thanks!
