I stumbled upon this, maybe it is something useable considering the state of the known mail web uis. Are they even activly supported atm? Roundcube and rainloop seem stall.
let me know what you think
Looks interesting but can't find anywhere to try it out. The one screenshot posted indicates it's pretty basic...Install is manual and via script, not ideal....Docker or NC app would be ideal...
[Edit] found some screenshots from couple of years back from the author of Cypht:
Your docker container
And a list of modules
