My best guess (and I am pretty sure about it) is that reason for delivering your mail in SPAM folder is wrong reverse lookup pointer of your public IP, on which your mail server is residing:

181.247.92.119.in-addr.arpa. PTR 86400 119.92.247.181.static.pldt.net.

It should reverse lookup into themail.fdamindanao.dyndns.org, but instead it resolves to 119.92.247.181.static.pldt.net, which is why your mail is placed in SPAM folder.

Solution:
Since you are on dynamic IP range, you have no option to resolve it. Best is to get static IP and then ask your ISP provider to add revrse PTR pointer, which would be exactly the same as forward A pointer of your domain name is.

Relay through another server?

[hmx_ryan]

Yes, we do have a Static IP... What should we tell to our ISP?

Tell them you want a reverse DNS for your IP.

fdamindanao.dyndns.org doesn't seems to have a mx record. Try add a mx record for your email server.

You need a MX record for domain fdamindanao.dyndns.org pointing to themail.fdamindanao.dyndns.org in your external/public dns setup.

In your public dns fdamindanao.dyndns.org config something like this:

@ MX 10 themail.fdamindanao.dyndns.org

You may not need the @ sign.

Also try adding a spf record too:

@    IN    TXT    "v=spf1 mx"
