Good night, I have a debian plesk apache vps, is it possible anyway to put the reverse dns of the email with proxy?
I intend to completely obfuscate the ip of the server, if necessary acquire a remote mail server to send another ip in the headers.
The aim is to block attacks on the vps, a way to separate the domain and the ip of the server, so as not to allow the information of the server and connections to all clients that browse the domain.
Can you help in the best way to resolve the situation?
I need to resolve the errors in dns configuration:
Reverse DNS does not match SMTP Banner
SOA Expire Value is out of recommended range
SOA Serial Number Format is Invalid
Information I found:
Best regards, RS.
