It's been years since I last did some serious email hosting, but it looks like the SPF rule is the problem.
Google is forwarding mail for dnalounge.com but the SPF rule doesn't allow Google's SMTP servers to do that: "v=spf1 a mx ptr ~all". That could explain why the email gets in the spam box; failing SFP should increase the "spam score".
Besides I think SOFTFAIL shouldn't be used in production; and I also doubt that Google should be taking seriously a SOFTFAIL anyway; so please take this comment with a pinch of salt.
SPF is easy to get wrong, and it always backfires at you ;)
