How to set up an answering machine

[Koful]

Hello everyone, I'm from Ukraine and I'm writing through deepl translator, so I apologize for my English.
I am using version 1.6.8 and need to set up an autoresponder for a while. I've looked at several instructions on the internet and what they say is not available for me, unfortunately.

And this problem is on all of my VPS
Help please

A autoresponder needs to be setup on the mail server since the email response needs to be sent out when a email is received and Roundcube only runs when you are using it so if your not available and not in Roundcube it couldn't send replies.

The thing is, I don't know where this is configured. I installed the HestiaCP panel and the mail server came with it

I'm not familiar with HestiaCP but according to https://forum.hestiacp.com/t/hestiacp-auto-reply/12937/3 you can set one up in HestiaCP under "List Mail domain → Click on Domain → Edit mail account then you are able to set an auto reply"

Thank you very much, I think this is it
