I'd definitively prefer an upstream-provided image if there was any.

Mailgun itself does in fact support multiple domains per account. If they are managed in the same account it should perfectly be possible to use them.

Currently, you have to specify multiple recipients and pass an `X-Mailgun-Recipient-Variables` header containing JSON-encoded recipient variables that can be used in your e-mail. Unfortunately neither this bundle nor Swiftmailer itself...

Would you like to have a PR?

Shouldn't this be possible by issuing `$redis->info('REPLICATION')` and looking at the `role` field in its result?
