Disabling mailcatcher commandline messages

When using mailcatcher for testing the sending of mails i use codeception and the codeception-mailcatcher-module. Everything runs as a Github action and i trigger stuff like this:

php vendor/bin/codecept run "tests/codeception/acceptance/product1/backend/RecommendCest" -v --html --fail-fast

That ways i get a very compact display of testing messages on the command line.

When a test contains mail testing, mailcatcher prompts large amounts of this messages:

*   Trying 127.0.0.1:1080...
* Connected to 127.0.0.1 (127.0.0.1) port 1080 (#0)
> GET /messages HTTP/1.0
Host: 127.0.0.1:1080
User-Agent: GuzzleHttp/7

* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< Content-Type: application/json
< Content-Length: 310
< X-Content-Type-Options: nosniff
< Connection: close

* Closing connection 0
* Hostname 127.0.0.1 was found in DNS cache
*   Trying 127.0.0.1:1080...
* Connected to 127.0.0.1 (127.0.0.1) port 1080 (#1)
> GET /messages/2.json HTTP/1.0
Host: 127.0.0.1:1080
User-Agent: GuzzleHttp/7

How can that be that made less verbose or completely disabled?

Here is the acceptance.suite.yml

      log_js_errors: true

error_level: "E_ALL & ~E_STRICT & ~E_DEPRECATED"

If my guess from the output format is correct, this is verbose logging of the curl HTTP client. From your description it is likely the guzzleRequestOptions:debug setting in acceptance.suite.yml for the codeception-mailcatcher-module :

modules:
  enabled:
    # ...
    - MailCatcher
  config:
    MailCatcher:
      url: "http://127.0.0.1"
      port: "1080"
      guzzleRequestOptions:
        verify: false
        debug: true
        ###########
        version: 1.0

Change it to false:

      guzzleRequestOptions:
        verify: false
        debug: false
        ############
        version: 1.0

And those message should not appear any longer.
