#Mutual Help [chatmail relay]I can’t pass the test after setting up my chatmail relay

Flowing the [guide](https://chatmail.at/doc/relay/getting_started.html), I’ve set up my chatmail relay and then ran commands `scripts/cmdeploy dns`, `scripts/cmdeploy test`. But two commands all failed.

 ![QQ20260503-172655](https://support.delta.chat/uploads/default/original/2X/4/4d502b4334a9101b9c59ed0acfa386ac31ad4d36.png)  
[Here](https://asciinema.org/a/vlGRJqPx2f8OI3a0) is the record of `scripts/cmdeploy test`, full log bellow (shown in a screenhot).

I have no idea what’s wrong and how to fix it.  
Many thanks if anyone can give me some advices!

I forgot about that people can successfully create accounts on my relay and chat with each other.  
But they can not directly chat with other accounts on any other relay NOR classic e-mail.

When one chat with accounts on other relays, client log shows `🔴 gralloc4: Empty SMPTE 2094-40 data`

Is the test result always the same? i.e. always the same tests fail, and always with the same error?

The problem is that at least for incoming connections port 25 of your server is blocked, this is why no incoming messages arrive. Probably the same for outgoing messages. You likely need to ask the hoster to unblock port 25 or disable some firewall.

You’re right. I just checked the VPS provider’s ToS, and it turns out they block SMTP and port 25.  
Anyway, thanks a lot for your help.
