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:

volumes:
maildata:

Telnet seems to only work on port 25:
$ telnet localhost 25
```Trying ::1...

(same result for three commands):

Hi @chrissound, what logs are saying when you try to connect with your email client?
tomav
on 9 Jan 2017
Not too sure which logs I should be looking at? The one in the docker stdout / stderror has no output when trying to connect via the mail client.
The only output occurs when I try port 25:
mail | Jan 9 14:01:36 mail postfix/smtpd[1398]: warning: connect to Milter service inet:localhost:8891: Connection refused
👍1
This line is useful! :-)
Port 8891 is for DKIM. Service is running? You have provided/generated keys?
tomav
on 9 Jan 2017
👍1
I don't think I have - I assumed it was optional. Will add this and report back.

mail | Setting up DKIM
mail | * No DKIM key provided. Check the documentation to find how to get your keys.
Yep, tell me first if DKIM is running.
If running but not working without config, I'll change this warning to an error (with an explicit message)
tomav

I've now added them the config file but haven't updated the dns zone - I'm testing this locally and do not have a DNS server (as far as I'm aware).
Is this possible to run just locally?

Better, it works now when you connect with your email client?

No I'm still getting the same issue.

chrissound
on 9 Jan 2017
Yep, so DKIM is running. What about the logs? Exact same output you had before?
tomav
on 9 Jan 2017
I've just tried change the SMTP port to 25 and get this in the docker output:
mail | Jan 9 15:43:31 mail postfix/smtpd[1944]: connect from unknown[172.20.0.1]
mail | Jan 9 15:43:31 mail postfix/smtpd[1944]: warning: TLS library problem: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1263:SSL alert number 48:

mail | Jan 9 15:43:31 mail postfix/smtpd[1944]: disconnect from unknown[172.20.0.1]
This is another issue. I think the SSL cipher is unsupported. What is your mail client ?
Thunderbird? Which version?
Could you try with another client?
tomav
on 9 Jan 2017
Yes Thunderbird 45.6, will try another. In the meantime I saw this command in the wiki (and pasting the result as well):
docker exec mail openssl s_client -connect 0.0.0.0:25 -starttls smtp -CApath /etc/ssl/certs/

Just installed Thunderbird 45.6.0, was plug and play to retreive and send email.

This certificate is autogenerated?

Not something I've done no - is this required?

Absolutely not required, postfix generated a default certificate, but won't be trusted by your client.
Try disabling SSL on your client.

I've tried this small python script:
import smtplib
server = smtplib.SMTP_SSL("mail.domain.com:587")
server.set_debuglevel(1)
server.login("[email protected]","chris")
server.sendmail("[email protected]", "[email protected]", "test")
server.quit()
With the following output:
Traceback (most recent call last):
File "index.py", line 3, in <module>
server = smtplib.SMTP_SSL("mail.domain.com:587")
File "/usr/lib/python3.6/smtplib.py", line 1029, in __init__

self._sslobj.do_handshake()
ConnectionResetError: [Errno 104] Connection reset by peer
Think I may need to set the encryption method though.

Could you try on port 25?

Same result.

I'm also not able to telnet successfully anymore it seems:
telnet mail.domain.com 25
Trying 127.0.0.1...
Connected to mail.domain.com.
Escape character is '^]'.
Connection closed by foreign host.
In your python script, have you changed smtplib.SMTP_SSL to smtplib.SMTP on port 25?
Otherwise it won't work.

What I guess is that you can't use SSL (you don't have a valid certificate).
Try on port 25 disabling SSL.

I've tried that script now with server = smtplib.SMTP("mail.domain.com:25") with same response / result:
smtplib.SMTPServerDisconnected: Connection unexpectedly closed.
I do see this in the logs though:
mail | Jan 9 16:29:44 mail postfix/qmgr[951]: 8C4F7425548: from=<[email protected]>, size=690, nrcpt=1 (queue active)
mail | Jan 9 16:30:14 mail postfix/smtp[1376]: connect to mail.domain.com[72.5.54.21]:25: Connection timed out
mail | Jan 9 16:30:14 mail postfix/smtp[1376]: 8C4F7425548: to=<[email protected]>, orig_to=<amavis>, relay=none, delay=79930, delays=79900/0.02/30/0, dsn=4.4.1, status=deferred (connect to mail.domain.com[72.5.54.21]:25: Connection timed out)
That does not occur again if I run the script again, so perhaps it's not related, no idea what it is (not the email address I used).

I've disabled spam assassin with this line in docker-compose.yml:
- ENABLE_SPAMASSASSIN=0
With same result.
