(See below for links) Even with those things set appropriately, you might just find that a 3rd party sender will be the only way to get reliable delivery; especially if you're hosting on a VM (e.g. Linode, Digital Ocean) rather than a full dedicated server with static IP that you know is "clean". Also, Google as a transport (using them for SMTP relay) is not a good idea. I know for a fact that as a paying Google Apps customer (with only two paid seats), I'm unable to send more than ~90 messages per hour. So, I'm moving to a 3rd party like SendGrid, MailGun etc. Finally, and not least of all, MediaWiki apparently still has a crufty internal email system. I haven't given these a try (because my mailing issue is with CiviCRM), but check out these extensions.
