SMTPUTF8 Support
Posted: Fri Sep 12, 2025 2:11 pm
Hello,
Does anyone know whether Zimbra (latest version) fully supports SMTPUTF8, and has this been tested?
I am currently considering whether to switch to Zimbra or not, and SMTPUTF8 support is very important to me because many email accounts rely on SMTPUTF8 support. In addition to Zimbra, I use Postfix (latest version). I have not been able to find any current information on this anywhere.
