My use case is a singleton HTTP server (no horizontal scaling). I already tried ECS, App Runner, Elastic Beanstalk among other tools. Every deployment option has minute+ downtime or otherwise takes minutes to complete. Is there any option on AWS to achieve instant deploy like Heroku? I simply want to restart my app with new code / new configuration.

All examples below are "From" headers in emails sent from various web services to our corporate email. This makes it look like we are sending emails to ourselves.

Some examples:

    "'Amazon Web Services' via Redacted - Admin" <admin@redacted.com>
    'Mezmo, Inc.' via Redacted Inc. - Admin <admin@redacted.com>
    'service@intl.paypal.com' via Redacted - Admin <admin@redacted.com>
    noreply-spamdigest via Redacted - Support <support@redacted.com>
    'Shopify Partners' via Redacted Inc. - Admin <admin@redacted.com>

Some notable exceptions:

    Heroku Billing Team <team.notifications@herokumanager.com>
    Wise <info@wise.com>

Questions:

1. What could be the justification for this practice?

2. Does this practice have a name?

3. Is this not considered spoofing?

4. Reading plainly, "X via Y" implies that Y is facilitating something on behalf of X, is this the intended reading?

I'm an IntelliJ user on M2 Mac, I've been testing VS Code out of curiosity and found it a bit slow, even simple things like "go to definition" have annoying latency.

Out of pure curiosity, is there any alternative to JetBrains in this regard? I am aware of LSP, but skeptical that it can ever be fast due to its client-server design.

Any programming language is fine as long as it has static types.

Some examples:

    "'Amazon Web Services' via Redacted - Admin" <admin@redacted.com>
    'Mezmo, Inc.' via Redacted Inc. - Admin <admin@redacted.com>
    'service@intl.paypal.com' via Redacted - Admin <admin@redacted.com>
    noreply-spamdigest via Redacted - Support <support@redacted.com>
    'Shopify Partners' via Redacted Inc. - Admin <admin@redacted.com>

It seems that most services are doing this. Some notable exceptions:

    Heroku Billing Team <team.notifications@herokumanager.com>
    Wise <info@wise.com>

What on earth could be the justification for this practice? How is this not considered spoofing?
