#Mailgun quietly cut off my access to its services without explanation, and through it I was sending e-mails from microservices like #PeerTube and all sorts of self-descriptive things.
Can you tell me about the existing OpenSource solutions for sending emails that I can setup and configure on my own server and domain? Or is it easier for me to write some simple HTTP-server basic API on #Go that will only send emails with the specified data by the request?
The problem is that I need a solution that only sends emails. I already have a mailbox set up in #HEY for Domains to receive emails.
