I'm using Bitnami Horde Groupware Webmail Stack 5.2.22-13 on Ubuntu 18.04 LTS. I'm be able to make it as my email client of my yandex.com mail account. No problem at all.
I can sent email in html format also. No problem at all.
the problem is when i trying to read my email in my inbox, it seems Horde are not displaying received email html correctly.
How could i fix this ?...
