Help configuring no-reply docker email server on linux VPS

Hi, I want to create a no-reply email on my vps using a docker mail server, I have followed the example to make a forwarding email, so I have created the email with docker exec -ti mailserver setup email add no-reply@jumblgram.com using this yml, but now I am unsure how exactly I can connect to that email in outlook for example. Also I am struggling on how I can activate auto renewal of the ssl certificate.

services:
  mailserver:
    image: ghcr.io/docker-mailserver/docker-mailserver:latest
    container_name: mailserver
    # Provide the FQDN of your mail server here (Your DNS MX record should point to this value)
    hostname: mail.jumblgram.com
    ports:
      - "25:25"
      - "587:587"
      - "465:465"
    volumes:
      - ./docker-data/dms/mail-data/:/var/mail/
      - ./docker-data/dms/mail-state/:/var/mail-state/
      - ./docker-data/dms/mail-logs/:/var/log/mail/
      - ./docker-data/dms/config/:/tmp/docker-mailserver/
      - ./data/letsencrypt:/etc/letsencrypt
      - /etc/localtime:/etc/localtime:ro
    environment:
      - ENABLE_FAIL2BAN=1
      # Using letsencrypt for SSL/TLS certificates:
      - SSL_TYPE=letsencrypt
      # Allow sending emails from other docker containers:
      # Beware creating an Open Relay: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#permit_docker
      - PERMIT_DOCKER=network
      # You may want to enable this: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#spoof_protection
      # See step 6 below, which demonstrates setup with enabled/disabled SPOOF_PROTECTION:
      - SPOOF_PROTECTION=0
    cap_add:
      - NET_ADMIN # For Fail2Ban to work
    restart: always
    stop_grace_period: 1m

    healthcheck:
      test: "ss --listening --tcp | grep -P 'LISTEN.+:smtp' || exit 1"
      timeout: 3s
      retries: 0

  certbot:
    image: certbot/certbot
    container_name: certbot
    ports:
      - "80:80"
    volumes:
      - ./data/letsencrypt:/etc/letsencrypt
      - ./data/certbot/logs:/var/log/letsencrypt/
    command: certonly --standalone --force-renewal --email <mail> -d mail.<domain> --agree-tos

This is not really a Docker question, but specific to the email server image and the application inside you want to use. I suggest you ask in their support forum.
