Description
Hi, Im wriing this issue just to ask for help for setting up docker-mailserver. Currently, I'm trying to develop some stuff and I need to run docker-mailserver on local(mainly to run tests). The IMAP server works fine but the SMTP server is another story...
I'm using smtplib in Python. This an example of script of what I am using to test the SMTP server:
import imaplib
server = smtplib.SMTP("localhost", 25)
server.login(f"[email protected]", "test")The error I'm running into looks like this:
> raise SMTPServerDisconnected("Connection unexpectedly closed")
E smtplib.SMTPServerDisconnected: Connection unexpectedly closed
/usr/local/Cellar/[email protected]/3.11.4_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/smtplib.py:405: SMTPServerDisconnected
My compose.yml looks like this:
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.mail.local
env_file: local-mailserver.env
# More information about the mail-server ports:
# https://docker-mailserver.github.io/docker-mailserver/latest/config/security/understanding-the-ports/
# To avoid conflicts with yaml base-60 float, DO NOT remove the quotation marks.
ports:
- "25:25"
- "143:143" # IMAP4 (explicit TLS => STARTTLS)
- "465:465" # ESMTP (implicit TLS)
- "587:587" # ESMTP (explicit TLS => STARTTLS)
- "993:993" # IMAP4 (implicit TLS)
- "5000:5000" # Localhost
volumes:
- ./docker-data/certbot/certs/:/etc/letsencrypt
- ./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/
- /etc/localtime:/etc/localtime:ro
restart: always
stop_grace_period: 1m
# Uncomment if using `ENABLE_FAIL2BAN=1`:
# cap_add:
# - NET_ADMIN
healthcheck:
test: "ss --listening --tcp | grep -P 'LISTEN.+:smtp' || exit 1"
timeout: 3sThe local-mailserver.env is the default mailserve.env( no SSL certifactes)
As stated before, I have no problems connecting to the IMAP server.
If you need more details, please let me know. Thanks in advance!
