Hi there,
I was just wondering why I am getting this error “This certificate has expired or is not yet valid” in Outlook and Thunderbird.
My mailcow runs smoothly and I am using a reverse proxy nginx. I use a certificate from letsencrypt.
Why am I getting this error every time I am receiving or sending email in outlook or thunderbird?
I would really appreciate your help.
THX

Hi there,
I would like to logon to mailcow with my own webui. So I am sending off a post request with my credentials and can logon only, if I disable web security on chrome. If I try to logon without disabling web security, I am not geeting in and it seems that a cookie was blocked! I am using an nginx reverse proxy and tried several settings like proxy_cookie_path ~^/(.+)$ ‘/$1; SameSite=None;Secure’; , but nothing works! can someone please help?

Hi there,
I am using mailcow with a regular domain www.myserver.com an a nginx reverse proxy. I was gonna use mail.myserver.com as well and notized, no matter which prefix I use “cowmail.myserver.com” etc, everything is working. So I can access my webui with any prefix!!! How can I change this? Furthermore, how can I get a valid ssl certificate for mail.myserver.com and myserver.com? It would be great if someone can help :-)

Hi Magic,
I made it work by changing the themes.js in /var/lib/docker/volumes/mailcowdockerized_sogo-web-vol-1/_data/WebServerResources/js. But if you restart sogo, it overwrites my custom settings again with the default ones.

Hi Magic,
thx, it worked :-). Do you also know, how to change the color of the logon screen on the right side?
Hi there, I would like to change the sogo logo. I tried to change the sogo-logo.png in /var/lib/docker/volumes/mailcowdockerized_sogo-web-vol-1/_data/WebServerResources/img, but nothing happened after a restarting with “docker-compose restart memcached-mailcow sogo-mailcow”. Can someone please help?

Hi,
thx for the reply. The API call only works, as long as I am using the “Allow CORS: Access-Control-Allow-Origin” plugin in my Chrome browser. As soon as I deactivate it, I am getting this: (Reason: CORS header “Access-Control-Allow-Origin” missing).
You have to set this either in nginx, or directly in the programming code! Where can I set this? For instance in nodejs I would handle it like this:
var cors = require(‘cors’)
app.use(cors())
Sending an ajax request from one domain to another without setting Access-Control-Allow-Origin, would be a security issue. Therefore it’s blocked. So does anyone know how to allow this in mailcow???

Hi there,
I would like to use the API in mailcow to create a mailbox. If I send off a request I am keep getting the following error:
“Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.”
I know this is a cross domain issue, therefor I have adapted the settings in
/opt/mailcow-dockerized/data/conf/nginx/site.conf
server {
root /web;
listen 80 default_server;
listen [::]:80 default_server;
include /etc/nginx/conf.d/server_name.active;
if ( $request_uri ~* “%0A|%0D” ) { return 403; }
location ^~ /.well-known/acme-challenge/ {
allow all;
default_type “text/plain”;
}
location /.well-known/host-meta {
default_type ‘application/json’;
add_header Access-Control-Allow-Origin ‘*’ always;
}
location / {
return 301 https://$host$uri$is_args$args;
}
}
server_tokens off;
proxy_cache_path /tmp levels=1:2 keys_zone=sogo:10m inactive=24h max_size=1g;
// file end
Anyway it doesn’t work!!! Can someone please tell me, how to allow posts from another server?
Regards
