Sent mails are marked as spam!

Greetings,

All the mails sent from any email id's from my organisation are marked as SPAM by all the standard mail providers (ex. gmail, yahoo, rediffmail, etc,.) 
I tried everything i could but couldn't get passed through the spam filter.

Added: SPF & DKIM records but still the same issue.

Please help me this issue, 
domain: eventurouznetworks.com

Thanks
