chore: Disable smtputf8 support in config directly (#3750)

* chore: Disable `smtputf8` support in config

This was always configured disabled at runtime, better to just set explicitly in `main.cf` unless config diverges when Dovecot is enabled to opt-out of this feature.

### Updates
- **Internal:**
- Postfix is now configured with `smtputf8_enable = no` in our default `main.cf` config (_instead of during container startup_). ([#3750](https://github.com/docker-mailserver/docker-mailserver/pull/3750))
- **Rspamd** ([#3726](https://github.com/docker-mailserver/docker-mailserver/pull/3726)):
- symbol scores for SPF, DKIM & DMARC were updated to more closely align with [RFC7489](https://www.rfc-editor.org/rfc/rfc7489#page-24); please note though that complete alignment is undesirable, because other symbols might be added as well, which changes the overall score calculation again, see [this issue](https://github.com/docker-mailserver/docker-mailserver/issues/3690#issuecomment-1866871996)
