Hi everyone, I’m facing a very persistent Postfix issue on a YunoHost server and I’m running out of ideas. I’d really appreciate any insight from people familiar with YunoHost’s mail stack. ### Logs: > **[hastebin](https://paste.yunohost.org/awupuqoqol)** The settings and error on Vaultwarden admin page: ![4p0dkqv](https://global.discourse-cdn.com/free1/uploads/vaultwarden/original/2X/0/0d9739f59d940dc54ae4a97960e84d890530180a.png) **Vaultwarden version** : 1.35.2~ynh1 **YunoHost version** : 12.1.39 **What type of hardware are you using** : VPS bought online ---

Having only looked at the last line of your post, I can almost guarantee you that your VPS host is blocking all email functions. Most all of them do. ---

Usually, I can send emails by vaultwarden when I tried to send from terminal there is no problem. What should I do?
