i recently checked my DNS on my side,
it's look normal for three MX records properly as it is mentioned here :

I also checked the SPF record, and it's working nicely without any error.
https://powerdmarc.com/power-dmarc-toolbox/?domain=fgroupindonesia.com&type=spf&selector=&ip=

But my question here is...
Why i can not send any email from this account (support [at] fgroupindonesia [dot] com ) anyway?

Regards,
