Mails configuration and DNS

Hi everyone,
I’m using Redash with Docker and I would like to know if it’s possible to change the IP adress (XXX.XXX.XXX.YY:5000) with a domain name in mails ? Any idea to do it ?

Capture

For example : XXX.XXX.XXX.YY:5000 → “myredash.com

Thanks in advance :slight_smile:
