My mail server is on Global Bad Senders list

Hello.

 

I have problem. My mail server (sendmail) was put on Global Bad Senders. When I want use remove bad reputation, answere is:

 

The IP address 90.177.98.17 was found to have a negative reputation. Reasons for this assessment include:

  • The host appears to be sending unauthorized email.

 

Bud I'm sure that my server is clear. I tested my server on open relay and some viruses. All tests were negative. I don't know where is problem and  what I have to correct.

 

Can you help me someone? 

 

Thank you very much,

 

Marek Pavlicek
