Linux DNS networking question:
MX record points to IP address
A record of a domain points to
18.104.22.168, can I still send emails from
22.214.171.124 on the behalf of a domain, without being classified as spam? The reason being this: I'd like to use
javax.mail to send newsletters from the application, but to receive personal emails on Google Apps to avoid possible Linux sendmail/qrunner exploits.
