Use 2 different server for send and receive email
<p>I have a classified website in a VPS. VPS are configured only like Web &amp; MySQL server. I actually use an external mail provider for send mail from cms used in website to users. I have configured DNS on Cloudflare like follow:</p>

<pre><code>domain-name.xxx in A [WEB SERVER IP]
ftp in CNAME domain-name.com
www in CNAME domain-name.com
domain-name.xxx in MX mail.provider.host priority 10
domain-name.xxx in MX mail2.provider.host priority 20
domain-name.xxx in TXT "v=spf1 include:spf-c.mail.provider.host mx a ~all"
</code></pre>

<p>Now i want use only noreply@domain-name.xxx (large number of emails are sent from this email address) with Dedicated mail hosting provider (it's not cheap but is affordable) and I want to use info@domain-name.xxx, or personal email accounts like name.surname@domain-name.xxx on another hosting provider ( cheap :-) ).</p>

<p>I'd like know if is correct adding follow DNS rules for use a second server (for info@ etc):</p>

<pre><code>domain-name.xxx in MX new.mail.host priority 10
</code></pre>

<p>I don't know if i must add any other rule.</p>
