Hello Community,

unfortunately, we have issues with the reply function in the forum. 
Whenever we want to reply in the forum, it will just timeout without any additional information.

Here are the logs result:

This issue just started from one to another day.
We think the mail function is the cause.

Has anyone solved this issue?

Many many thanks in advance.

best regards,
