Should I have a seperate Mail Server Host address for each email domain

Hi All,

I'm working on an Exchange 2010 Email server and corresponding MX records for each of it's several email domains.

Currently the DNS records for each email domain have a MX record that points to a mail host called mail.emaildomainX.com  (i.e. one for each email domain)

All the mail.emaildomainX.com addresses actually point to the same server.

Do I need to do this or is this the best way because it helps when spam engines check out emails sent?

Hi,

From personal experience i tend to put in a host for each domain and an spf record.
Its more work but tidier and if anything happens to the main domain then email for the others will continue.
We deal with quite a few domains on our server and we manage each as a seperate entity in this way.

Thanks
Andy
