Disabling DMs based on user roles would be a nice addition. I want to disable members sending DMs to one another, but still be able to send them DMs as admin of the server.

As I mentioned in mattermost/mattermost#2440 (comment) the DM-UI needs some polish to make it viable in a educational context.

Right now the plugin blocks DMs to a user and displays this as follows:

In cases where sending DMs is blocked the user is still able to create a new DM-Channel which then doesn't work. A more intuitive approach would be to hide the plus button next to "direct message" so users on an instance with disabled DMs can't even open a new DM-Channel.

make: *** [Makefile:162: build] Error 1

Expected behavior:

• Creating "mattermost-plugin-disable-dm-v<X.Y.Z>-linux-amd64.tar.gz" in /dist

So, the go developers decided to remove the "experimental" checker shadow (see golang/go/issue/29260 and references therein). This means that the Makefile throws an error at line 69 where it tries to run @$(GO) vet -shadow $(PKGS):

Running GOVET
vet: flag "-shadow" not defined
Run "go help vet" for more information
make: *** [govet] Error 2

Taking the brualist approach and deleting that line allowed the build to complete. It would be great if the Makefile was corrected at source, please.

Hello,

Would be great to have a feature to whitelist some users/channels.

Thank you!

Hi!

I'm trying to implement this plugin into my mattermost setup. I've enabled plug in and am in need of uploading the plugin, but I can't seem to make the dist directory.

This is the error I get:

Running GOVET

I've tried making systemlinks, but that didn't work :(

Any help would be greatly appreciated! Alternatively, if anyone has the built version I can upload to my mattermost team that would be great too!

Thanks!

Hello!

I think it would be useful to have binary releases for this plugin like this

Thank you!

hi all

can somebody help us? we install the described versions, but became this issue on create it.

Running GOVET
go vet: can't execute /bin/shadow -flags: fork/exec /bin/shadow: no such file or directory
Makefile:62: recipe for target 'govet' failed

or can somebody send me the linux dist plugin file? on release it is included an .exe file

thank you for helping

Hi, I'm trying to run a mattermost server for my children and their friends learning during lockdown.

I'm running the team edition.

I want to disable all mechanisms for users to send private messages to each other. This includes direct messages, group direct messages and private channels. Ideall I, as sysadmin would still be able to send them, but this isn't essential.

I've installed this plugin and it works great for disabling private direct messages.

However, because I'm running the team edition, I can't use the new permissioning system in mattermost. The ability to turn off private channels seems to have been a feature in v4, but in v5 it's only available to people running paid versions of the server.

Is it possible for this plugin to also restrict users from creating private channels?
