Is TLS generally not set for Cloudrons E-Mail Server, because all version are not safe?

What do you mean by this? Cloudron has so called opportunistic tls - https://en.wikipedia.org/wiki/Opportunistic_TLS . So, if your destination server or sending server can handle it, Cloudron will switch to TLS always.

If you "view source" in your mail client, you will see them. Yes, this is the default.

It is. If you are using DNS, in which Cloudron supports it, it sets the needed default parameters for proper operation.

DMARC is a protocol that uses SPF and DKIM to detect email spoofing. For DMARC validation to succeed, along with SPF or DKIM check, DMARC alignment needs to succeed as well.
