Update: I was faster then my provider. The problem is solved. My dns mail is no longer against rfc rules. You can send emails to the blog email adresses.
I’m so sorry at the moment 1and1 (united internet) customers, e.g. 1and1.com, GMX or Web.de, can’t send any emails to me. I know why it is so and I and my provider try to solve the problem.. In the meantime, if you are an 1and1 customer and you want to send me an email, you can use the “ask form” or the email adress [email protected]. I would like to apologize for any inconvenience, Once the incident is resolved, I’ll announce this at this point. Many thanks for your understanding. Greetings, EmoBCSMSlave
