The Sender Policy Framework (SPF) is a great tool to help validate email senders and detect email spoofing. We recommend that all domains have a proper SPF record configured for this reason. However, SPF has long caused problems with forwarders and this is now no longer an issue. As of cPanel 54, which was installed on all servers earlier this month, Sender Rewriting Scheme (SRS) is fully supported out of the box. Previously some forwarded emails would get rejected by the destination mail server due to the SPF check failing. SRS now automatically rewrites the envelope sender such that forwarded emails will still pass SPF checks. You don’t need to do anything to activate SRS, it was enabled on all servers on March 9th.
Last week another batch of clients was migrated to our new billing system that is built-in to our existing portal. The response has been overwhelmingly positive as it eliminates a lot of unnecessary confusion with having a separate billing system. We hope to have all of our clients migrated within the next month or two and appreciate any feedback you might have.
Lastly, we will be resuming our server upgrades in the upcoming month (April). These took a backseat while we finished up our billing system and continued evaluating the servers that had already been upgraded. Thus far we are very pleased with these upgrades and, like you, we can’t wait to have everything migrated to pure SSD environments. You’ll receive a notification when your server is scheduled to be upgraded if it hasn’t been already. We expect to have all remaining servers upgraded by the end of August.
