I do not receive email on specific providers

Ubuntu Email Networking Messaging Applications

I have followed this setup (https://help.ubuntu.com/community/PostfixVirtualMailBoxClamSmtpHowto) without the clamav part. For the last days it works pretty good.

After that i dont recieve email at mail-tester.com and hotmail.com. Other email adresses are properly working, like Gmail.

The logs are as follows:

It looks good (status=sent). But mail-tester.com never receives it.
DKIM and SPF are good.

What can be the problem?

Mail test did receive it - http://www.mail-tester.com/web-mE2sIR

Hotmail is too picky and doesn’t like receiving emails from new mail servers even if they are signed and have proper records.
