Let's say I have a domain that I run a web application on, for example
cranketywidgets.com, and I'm using Google Apps for handling email for people working on that domain, for example,
email@example.com and so on.
Google's own mail services aren't always the best for sending automated reminder emails, comment notifications and so on, so the current solution I plan to pursue is to create a separate subdomain called
mailer.cranketywidgets.com, run a mail server off it, and create a few accounts specifically for sending these kinds of emails.
What should the
MX records and
A records look like here for this?
I'm somewhat confused by the fact that
MX records can be names, but that they must eventually resolve to an
A record. What should the records look like here?
A record to actual server like 10.24.233.214
MX records for Google's email applications
MX name pointing to server's IP address
I would greatly appeciate some help on this - the answer seems like it'll be obvious, but email spam is a difficult problem to solve.
