Send email from server - Domain/IP blacklisted

Hi everyone,
I need a simple solution to this.
Outlook is completely blocking emails sent from my domain.
I don't use any spamming.
I only send log information to my outlook email.
It worked before but now my logs are completely gone.
What would be the simplest way to make this work again?

Appreciate your help.

are your ips are dedicated? Have you checked if your ips are blacklisted or not? Have you checked the content for spam words? Is your domain is properly configured to send emails I mean the spf and dkim settings?

I suspect that my domain or IP is blacklisted in a database somewhere on the email hosting provider for outlook.com.
I couldn't find any public lists where my stuff were blacklisted. Tried the mxtoolbox
However, if I start to work with SPF and dkim I suspect it will not help. Maybe after a week. I don't know.
Is it possible to do it like this myserver->emailhosting ->outlook.com ?
I know for example that outlook allows me to forward emails to another email.
I'm going to check if I can do this with Gmail.

I fixed this with GMail.
