Postfix SMTP Relay related

[NightNeon]

Hi Guys, I'm having problem on my postfix mail server,
I'm trying to send email to outlook.com / hotmail.com but no luck, not even reject or into recipient spambox.
try my luck to talk to outlook support, no luck.
I decide to route my email to other mail server to resolve this issue. I have no clue on how to search the solution on google...
How can i do that in postfix,
what i want to filter when sending email to outlook.com/hotmail.com will relay to other mail server....
is that possible?
Sorry I'm very new to mail server......

Hi

did you have port25 output open ? In general hotmail and gmail are very restrictive to new mails servers, you may need to configure some authentication methods like SPF and DKIM. Check if your IP are in some blacklist, try this
