Congrats on 5.0 - CoScreen has been an integral part of our team's daily workflow for the last couple of years, and it's been wonderful to to be able to share feedback and see the product evolve into a better and better tool.
Having to share screens occasionally via Zoom feels so slow and clunky by comparison to the single-click ability for multiple people to share and interact with windows concurrently as the conversation flows. Can't imagine going back!
I've been hosting my email on my own server since the 90s, but got tired of dealing with keeping up with spam filters. Updated the MX to deliver inbound to mailroute.net and have them do the filtering before forwarding to my server and that's been working great for years. Not free, but not expensive and still gives me 99% of the control i want with very good spam filtering too.
Outbound mail is relayed via mailroute too, which solves the tainted IP delivery problem.
