Mailcow logs viewer: A faster, cool way to monitor your emails

shlomi · 2025-12-25T18:47:39+00:00

Hi everyone, While mailcow is an amazing suite, I often found the built-in log viewing options a bit clunky when I needed to debug something quickly (its ev...

I don’t know where the folder is located.

The directory where you installed your mailcow-logs-viewer. You don’t know where you installed it?

For example:

root@mailserver:/root# ls -la /opt/mailcow-logs-viewer/data/
total 66604
drwxr-xr-x 2 monitoring monitoring     4096 Feb 16 12:53 .
drwxr-xr-x 9 root       root           4096 Feb  6 08:01 ..
-rw-r--r-- 1 monitoring monitoring     1271 Feb 18 12:54 container.log
-rw-r--r-- 1 monitoring monitoring 11461381 Feb 12 09:15 GeoLite2-ASN.mmdb

Did I miss something in the instructions?

[root@mail /]# ls -la /opt/mailcow-logs-viewer/data/
ls: cannot access '/opt/mailcow-logs-viewer/data/': No such file or directory

DocFraggle

maybl8 Where is your mailcow-logs-viewer installed to? Is it /opt/mailcow-logs-viewer ? Or maybe somewhere else?

[root@mail opt]# ls

DocFraggle

maybl8 I gues you have an old version of the docker-compose.yml

ShlomiPorush/mailcow-logs-viewerblob/main/docker-compose.yml#L31-L32

Check this

DocFraggle
Ok docker-compose.yml updated.
and the icon works but I don’t know where the data folder is:

[root@mail mailcow-logs-viewer]# ls -la /opt/mailcow-logs-viewer/data/
ls: cannot access '/opt/mailcow-logs-viewer/data/': No such file or directory

Can’t get the webpage to show again.
I have checked everything.

I actually forgot to thank @shlomi for the update.
Thank you for storing all JavaScript and CSS files locally now, which greatly improves data protection.

I found it here but there must be an easier what to find it.?

/var/lib/docker/overlay2/be93b26d6c9b8ce34fbef707dfd3df6149c27daed756e09162a616a80025fa77/diff/app/data/

Just came across this and installed it. Great tool!

I found it best to add a virtual host to nginx-mailcow and use it as a reverse proxy towards http://mailcow-logs-app:8080;

If anyone’s interested in the extra config for nginx, I’ll be happy to post it here.

maybl8 I found it here

That’s just the data directory mounted into the docker container… check your docker container where the original directory is located:

docker inspect -f '{{json .HostConfig.Binds}}' mailcow-logs-app

In my setup:

["/opt/mailcow-logs-viewer/data:/app/data:rw"]

which means it’s /opt/mailcow-logs-viewer/data

DocFraggle
I think something is not setup right.
I know I have a container.log somewhere. I just don’t know where.

[root@mail mailcow-dockerized]# docker inspect -f '{{json .HostConfig.Binds}}' mailcow-logs-app

null

docker inspect mailcow-logs-app

maybl8 Please check if you really have

    volumes:
      - ./data:/app/data

inside your docker-compose.yaml. Doesn’t look like it…

OK, something is VERY strange on your system. If the data directory does not exist in your compose project directory it would have been created as soon as you stop and restart your project. Don’t know whats going on there.

I know there is a log file somewhere because when I click the button on the bottom of the mailcow-log viewer I see this:


container.log

During handling of the above exception, another exception occurred:

app.mailcow_api.MailcowAPIError: Failed to connect to mailcow API: [Errno -3] Temporary failure in name resolution

So there is a log going somewhere.

I thought the problem was with this line:

- postgres_data:/var/lib/postgresql/data

I tried to follow that path and all i had was

/var/lib/postgres

That didn’t make a difference so I put it back and restarted the stack.
But now I have this message when clicking the icon

container.log
Log file not found or hasn't been created yet.
