Mx Problems

[Max27]

Hey Guys. First of all: Thanks for trying to help. My problem is that im very confused about my business email. I connected my email with the domain, got dmarc, spf and so on. I am able to receive and write emails. But when i sent emails there is always the sign of possible spam. And when i check my domain in the mx check it shows huge problems like missing mail server, missing dmarc, missing spf, missing dkim and so on. But when i check it in the terminal it doesnt show any problems. Please help me to get aware of the problem and fix it. My domain is urbanup-media.com . Its so confusing. Thanks in advance and have a great day!
