problem with email reverse dns and using email on multiple domains

[nsarantopoulos]

i am planning to buy a dedicated server together with cpanel but there is a frustrating problem all the email for different domains goes spam cause there is no reverse record but if i put reverse dns it will be for only one domain and not for the rest of the domains that i will create for my customers is there a solution for this cause a reverse ip cannot be used for every email domain

thank you

The PTR record (rDNS) should resolve back to the same IP the hostname of the server uses and can most certainly be used for every domain on the server. This isn't something you can typically add though, usually this is something the hosting provider or data center does not delegate access to.
