Send eMail error UTF-8

I would like to send an eMail out of OH3.
Whenever I trigger the very simple rule - completely striped to the basics - I‘m receiving the following error messages:

2022-05-30 21:37:15.715 [WARN ] [ab.binding.mail.internal.SMTPHandler] - javax.mail.MessagingException: IOException while sending message;
nested exception is:
javax.activation.UnsupportedDataTypeException: text/plain; charset=UTF-8

The stripped rule:

var mailActions = getActions("mail","mail:smtp:ef46799f24")
var success = mailActions.sendMail("andreas@xxx.xx", "Test", "Hallo")

—> @xxx.xx is of course a real eMail address

Any idea?

Thank you and best regards

What openHAB version are you running ?
The error you describe had been solved with Milestone 5.

Thank you for the information.
I’m running OH 3.2.0 and also the mail binding 3.2.0.

What can I do?


You need to update your openHAB to the latest milestone release or wait for the upcoming 3.3 release which is scheduled for end of June…

Hi hmerk,

I’ll try to update the environment.
Thank you very much for your help and hints.
Best regards
