[MM3-users] Held messages: Long time waiating for response of the Mailman API

Hello,

We are using Mailman 3.3.5 with Hyperkitty 1.3.5. Mailman 3 is installed in a venv and deployed using Apache and uwsgi. This works quite well so far, only withheld messages cause us a problem: If we try to approve them via Postorius, the message is delivered to the list immediately, but the success message in Postorius takes a long time - on average the process hangs for three minutes until the message is no longer displayed. We have already adjusted the timeout in gunicorn.cfg, but this does not improve the situation. Are there any tips on how we can speed up the REST API? Or is it even a configuration error?

Greetings

Stephan
