Evitar que mis correos sean marcados como spam usando registros PTR, SPF o DKIM

Hello. I am linux administrator with 4 years experience. I can help you with your email server. I did it many times here you can see in my feedback. You need install opendkim service. This is my plan - checking email on [login to view URL] . And fix step by step all warnings DKIM(installing opendkim service), mx, sfp records. Also important thing is setup time sincronization. I know how to do it all. I will need ssh acceess to server and access to DNS panel to help you.
