Hey, I created a droplet using the LAMP on Ubuntu 14.04 Application. And apt-get installed postfix and mailutil. Any time I send an email to Gmail it goes to the spam folder. My Zone file is as follows:
$TTL	1800
			1402857717 ; last update: 2014-06-15 18:41:57 UTC
			3600 ; refresh
			900 ; retry
			1209600 ; expire
			1800 ; ttl
             IN      NS      NS1.DIGITALOCEAN.COM.
                     NS      NS2.DIGITALOCEAN.COM.
                     NS      NS3.DIGITALOCEAN.COM.
			MX 10
*.api	CNAME
*.www	CNAME
@	IN A
www	IN A
api	IN A
@	TXT	"v=spf1 ip4: ~all"
mail	IN A
*.mail	CNAME
And the received email is as follows:

I've tried editing the SPF1 record and MX record. I've renamed the droplet to I'm not sure why it's still failing and what I can try next?

Setup DKIM. It will help authenticate your emails but still isn't a guarantee that Google will mark them as spam. Email is a hair pulling game and a lot of people decide to use third party options like Google Apps,, or
Thanks jt, I doubt that will make a difference as it's not set when mail is sent from Gmail but I'll give it a try.
My mistake - DKIM is set by Google. I added opendkim but it didn't make a difference. Emails are still flagged as spam. I signed up to Zoho and it works which is great. But I'd still like to figure out how to get emails working without having to use a third party.
