New features and events
With the events at the end of April / beginning of May behind us, we’re getting back to the new features and client requests in our core products. We executed a massive upgrade to the core of the ExchangeDefender network which now gives us the capacity to start implementing more layers of protection and functionality in email. Here are some news and a request.
.US tld – Over the past month we have seen a massive and coordinated SPAM storm using .us and new extended/vanity top level domains. They all follow the same pattern: all use .us tld, all are registered with a foreign agent/contact, all have properly setup rDNS, SPF records and DKIM auth (which even few legitimate .us mail servers have) and all come within a 24 hour window until the domain and VPS the storm originated from is destroyed. One interesting catch is that they do not process or acknowledge non-delivery receipts. We’ve had an unusual spike in complaints about SPAM levels all linked to the .US tld and since May 9th, 2017 we have rolled out a new set of rules to filter this content out. We are not blacklisting the tld, legitimate mail will still pass.
TLS issues on ExchangeDefender – We have finally decomissioned the TLS v.1 / SSL v.3 protocols on our inbound network and implemented more strict SPF record checking. This means that those old, unpached servers if any are still left will be forced to either send mail in plain text or upgrade their SSL implementation.
Public Folders, Shared Mailbox, etc – What do you hate about them? This is an open ended question, please feel free to send an email to vlad@ownwebnow.com with subject “Public Folders” and tell us what you’d like to see. As you may imagine, everyone uses and manages stuff differently so we want to see what we could change in our approach and control panels to allow for this to be done easier and quicker. We have folks using Outlook to manage them, we have folks using our control panel, we still have people that try to create a folder and give the whole world access to it (bad!) so if you’ve been frustrated by what we’re currently offering or if you’d just like to see something added, we’d love to hear about it.
