I've build a simple Mail server for my personal use, but Google reject my emails whatever I do.
I worked hard finding the initials problems (wrong SPF entries in the DNS), but now, everything seems fine, and I still got this kind of messages from Gmail :

Hi. This is the qmail-send program at myserver.ovh.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out.

My domain is mediafins.com, here's the SPF entry related to it :
v=spf1 a mx ip4:18.104.22.168 ~all
(The ip is the IP to my server).
I also tried this (interesting tool) : http://mxtoolbox.com/public/tools/findproblems.aspx?filter=22.214.171.124/29&source=findmonitors&domain=mediafins.com
The only problems are related to HTTPS, everything else is good.
Having "everything else good" is what bother me : if it's good, why Google still reject my emails ??
What did I do wrong ? Do I have to add a SPF also to mail.mediafins.com, my MX DNS entry ?
Thank you for your help, I really appreciate !
