I have a Docker stack for my mail server.
My docker-compose.xml
contains
version: '3.7'
services:
postfix:
...
dovecot:
....
ports:
- "110:110"
- "995:995"
- "143:143"
- "993:993"
networks:
- mail
....
roundcube:
image: roundcube/roundcubemail
container_name: roundcube
environment:
- ROUNDCUBEMAIL_DEFAULT_HOST=dovecot
# - ROUNDCUBEMAIL_DEFAULT_PORT=993
networks:
- proxy
- mail
I also have a Nginx container running as a proxy for all my web applications. For roundcube I have
set $roundcube_upstream http://roundcube;
location /roundcube/ {
rewrite ^/roundcube/(.*) /$1 break;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header Host $host;
proxy_pass $roundcube_upstream;
}
With that configuration it's working. I can go to https://www.mydomain.be/rouncube/ and I can login. The default port is 143. So roundcube si connecting to dovecot with imap.
Now, I'd like to use port 993 and ssl/tls.
I tried decommenting the ROUNDCUBEMAIL_DEFAULT_PORT=993, but also using ssl://dovecot or tls://dovecot or ssl://mail.mydomain.be, ... but nothing is working.
When I click on the connextion button, after a while I receive an nginx error page. In my proxy logs I can see
2019/01/31 09:29:25 [error] 460#460: *82483 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 194.197.210.75, server: www.mydomain.be, request: "POST /roundcube/?_task=login HTTP/1.1", upstream: "http://172.18.0.9:80/?_task=login", host: "www.mydomain.be", referrer: "https://www.mydomain.be/roundcube/"
And I don't understand where the http://172.18.0.9:80/?_task=login is coming from ?
With Thunderbird client I can connect on that port.
What's the problem ?
Edit
Using
- ROUNDCUBEMAIL_DEFAULT_HOST=ssl://dovecot
- ROUNDCUBEMAIL_DEFAULT_PORT=993
I now have a response : connection error to the storage server.
In my roundcube logs :
errors: <1db522a3> IMAP Error: Login failed for me@mydomain.be from 172.18.0.8(X-Real-IP: ...,X-Forwarded-For: ...). Could not connect to ssl://dovecot:993: Unknown reason in /var/www/html/program/lib/Roundcube/rcube_imap.php on line 196 (POST /?_task=login&_action=login)172.18.0.8 - - [31/Jan/2019:13:57:37 +0100] "POST /?_task=login HTTP/1.1" 200 3089 "https://www.mydomain.be/roundcube/?_task=login" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0"
and in dovecot logs
2019-01-31T13:57:38.002653+01:00 536ff3507263 dovecot: auth: Debug: auth client connected (pid=35),
2019-01-31T13:57:38.010096+01:00 536ff3507263 dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.240.3, lip=192.168.240.2, TLS, session=<nVssksCAT7LAqPAD>
So dovecot is well contacted but ... ? Don't know whats the problem.
