Emails not going from Mandrill to Gmail

Question

I'm trying to send email from my app, emails seem to be going to mandrill correctly and there getting delivered, but I see nothing in my inbox.

I've even tried sending them through my domain and I'm still not getting them. I get them from my live website its using gmail but I want to switch

Using mxtoolbox.com I found

SMTP Reverse DNS Mismatch and 454 4.7.1 Relay access denied which could mean its been marked for spam?

It's sent through emails twice so I'm wondering if theres a time between emails sent or something.

Answer 1

When I was testing this I thought my emails where being dropped by gmail. I found that for some reason there was a very long lag going from Mandril to Gmail. I received all my tests about an hour after Mandril sent them. Hope this helps someone stuck like I was.
