This tutorial recommends VERP + mail-receiver, but handling all my incoming emails myself on my own VPS, that’s impossible for me since I need a functional mailbox, so I reserve the MX record specifically for another provider (because there can only be one MX record per domain).
The other technique is using webhooks, and I think it’s great, however, I don’t like any of the supported email providers.
Will I have to create my own script to handle bounces via webhooks and have it work with my own provider or do you have some kind of template that does this in a trivial way? Can I skip the whole VERP/bouncing thing without a problem?
