setting up dd-wrt dns records correctly would help

https://mxtoolbox.com/SuperTool.aspx?action=smtp%3a185.84.6.188&run=toolpage

Code:
Connecting to 185.84.6.126

Code:
telnet 185.84.6.126 25
220 mail.as201155.net ESMTP ready.

telnet 185.84.6.188 25
220 mail.as201155.net ESMTP ready.

Well how to fix this - depending on who you ask Smile
    * either add the IP 185.84.6.126 to mail.as201155.net and add the reverse PTR
    * find out why there is a DNS Record pointing to 185.84.6.126
and yeah - some other shit is coming directly from redmond
