Struggling to find the usecase for apprise, I think I’m missing something major :D

Can you run apprise centrally and have it receive on multiple channels (smtp, webhooks, maybe syslog etc)?

I.e. can you have it independently hosted and apps/services send messages to it which are then forwared by apprise via the preconfiged channel (email, discord, signal etc.)

My scenario is (simplified):

I have homeassistant automations running which send smtp messges to a local smtp relay which forwards the emails via gmail to me.

I now have a requirement of another server that sends notifications via a webhook (that is the only supported method).

How can I receive messages on multiple different channels (smtp, webhooks, maybe syslog etc) and send via smtp (or something else I choose in the future). Is apprise going to help here?

TIA!
