Hi there,

I have a chat relay running on a _raspberry pi_ and it’s working really fine. Now after some time I want to change certain parameters like max message size. I found some posts about this topic but I don’t really understand some things.

-Where can I find the mentioned _chatmail.ini_ file?  
-How do I apply these changes? (? ./scripts/cmdeploy run ?)  
-Can I apply them directly on my relay or do I have to do it from my local machine like in the initial setup using ssh?

Sorry for my amateur questions.

Greetings, broncheolus

It should have been created by `scripts/cmdeploy init`. You can also recreate it from scratch if you have lost it.

Yes, to apply changes you run deployment the same time as when deploying the first time.

“Supported” way is using cmdeploy. If you know what you are doing and understand where the config is applied you can of course tweak the postfix or dovecot config directly, but then the changes will be lost when you use cmdeploy to upgrade.

Just to mention:

Today I tried to apply my wanted changes to my relay. I resized user memory to 2 GB and max Filesize to ~350 MB by editing chatmail.ini file. And what can I say, deploying worked and the changes are made.

Thank you so much for your help.
