Hello all.
This is my first post as well as working in a linux server.
I currently host websites for my customers on a shared server with a single ip address. Recently, a user's computer became compromised and began spewing spam from my hosted account resulting in being blacklisted. I purchased a dedicated server with 20 ip addresses to assign to each domain I host. I want each domain to have a dedicated ip address for email inbound and outbound. This way if a domain begins to send spam, it does not impact my other customers.
I'm looking for guidance on accomplishing the following:
I intend to use postfix for email.
Creating virtual domains in postfix.
Assign hostname to each ip IE: mail.abc.com 1.1.1.1, mail.xyz.com 2.2.2.2
Configure postfix to send email from the ip that matches the domain name the user belongs to.
I have completed the DNS updates along with MX and SPF.
Any help would be great.
Thank you,
Eddie
