Not delivering campaign

I just finish setup a server today.. I test to 5-6 my own email (seed list) and all good, the i loaded 500 emails including mine and send it..

But no email deliver to my email.. I mean looks like campaign not deliver while it says it does..

Then i send again to seed list it went smooth

Then, i send out to 500 leads and all went to spam box.. Anyone can explain this situation or solution?
