I am not going to flame this... much, but I am curious - you say you have had a good experience with version 16...
To the point, what percentage of your customer-base utilizes the webmail system vs. client-based?
We have had all the same issues reported by others in the November-December, but the continued and ongoing interface issues in webmail are frankly burning down the house, and not in a good way.
We have witnessed our SM usage via webmail drop by over 80% since moving to v16 in late September. We have had over 1000% increase in tickets including a lot of complaints by our user-base, which is nowhere as large as many who are reporting issues. And do you know what? There has not been one, not one single user who opened a ticket to report an issue or complain who likes the SM16 interface approach. I for one use SM16 via webmail every single day for the sole purpose to inflict as much pain and punishment on myself as possible for authorizing the decision to upgrade to v.16.
Smartermail 14-15 was considered by nearly 99% of our customers to be the best webmail experience available.
I am not saying that v16 does not have some good ideas, just that there are too many broken and incomplete parts that make it an irrational decision for serious email functionality.
As for the SM team, time will tell us how this SM16 debacle will ultimately be decided.
Let me know your webmail vs client usage - because my suspicion is that webmail-centric providers are being slammed the most.
