Hi Signoz Community, I’ve recently set up Signoz using Docker Swarm and have configured the Alertmanager service to connect to our corporate Exchange server. Here’s what I’ve done so far: • Set up the necessary environment variables to connect to our Exchange server. • Added the email channel for alerts. However, when I click the Test button for the email channel, I encounter the following error:

signoz_alertmanager.1.d7salrmoi6bk@srv-exc | level=error ts=2024-10-29T10:37:17.607Z caller=api.go:808 component=api version=v1 msg="API error" err="server_error: establish connection to server: dial tcp [::1]:25: connect: connection refused"

To troubleshoot, I tested the connection details (username, password, etc.) using swaks, and the server responded with:

Auth not attempted, no advertised types available
<- 250-X-EXPS GSSAPI NTLM

It seems that the Exchange server only accepts GSSAPI NTLM and not BASIC authentication. How can I configure the Alertmanager service in the Docker Compose environment to use GSSAPI NTLM for authentication? Thank you
