docker-mailserver: Unable to connect via email client

I’ve added a user, verified it by using the setup.sh script (setup.sh email list).

I’m trying to use Thunderbird and add the account but get a “Thunderbird failed to find the settings for your email account”.

Perhaps there is a console email client I could potentially use to test this and get a more informative error message?

I’ve set it up as stated in the wiki here: https://github.com/tomav/docker-mailserver/wiki/FAQ-and-Tips

I’ve also added the following to my hosts file:

127.0.0.1	domain.com
127.0.0.1	mail.domain.com

I’m using docker-compose with the following configuration:

  mail:
    image: tvial/docker-mailserver:2.1
    hostname: mail
    domainname: domain.com
    container_name: mail
    ports:
    - "25:25"
    - "143:143"
    - "587:587"
    - "993:993"
    volumes:
    - maildata:/var/mail
    - mailstate:/var/mail-state
    - ./config-mail/:/tmp/docker-mailserver/
    environment:
    - ENABLE_SPAMASSASSIN=1
    - ENABLE_CLAMAV=1
    - ENABLE_FAIL2BAN=1
    - ONE_DIR=1
    - DMS_DEBUG=1
    cap_add:
    - NET_ADMIN

volumes:
  maildata:
    driver: local
  mailstate:
    driver: local 

Telnet seems to only work on port 25: $ telnet localhost 25

Connected to localhost.
Escape character is '^]'.
220 mail.domain.com ESMTP Postfix (Ubuntu)

telnet localhost 143 telnet localhost 993 telnet localhost 587 (same result for three commands):

Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
