If you need to send (and have better than 50% get through) and receive you're probably going to set up a service like Fastgmail to handle receiving and personal sending and send your automated mails out through something like mailgun, SES, sendgrid, etc.

You have to properly set up your DNS records so that all your sending servers authenticate properly.
