New to bitwarden on-prem email setup

I just installed bitwarden on-prem using the instructions when i login as a user and try to send a verification email i see the check your inbox notification but I never get any email. I’ve already restart the server after i made the modifications to the file below.

My current setup inside ./bwdata/env/global.override.env

[email protected]
globalSettings__mail__smtp__host=ip address of internal mail relay

What else can I do to get this to work?

I was able to resolve this by updated to 1.30.0 from 1.29.0, it seems like the 1.30.0 release resolved some issue with smtp mailing.
