All E-mails directed to Hotmail from any mail account get rejected
I’m having a VPS running on Ubuntu 14.04, IP: 18.104.22.168 and for some reason any E-mail that is sent to a hotmail account (tested with both an existing as a just newly created one) is not being received. Any other E-mail account (i.e. Gmail) has no problem.
As far as I would say everything is set up fine, but we can simply say apparently it is not.
My VPS FQDN is iscs.nl which is my main (business) domain. But on that same server, other clients of mine are hosted. One of those (Testing with this one and my business domain) is verboonhoveniers.nl.
I’ve set up dynamic DNS (as much as possible, excluding PTR), so that the mail DNS gets mail.<domain>.<tld>. Or in exact cases, mail.iscs.nl or mail.verboonhoveniers.nl. However of course: The main domain of the VPS remains iscs.nl as this cannot be set up dynamic.
Sending a test E-mail and posting the log of that E-mail /etc/log/mail.log below

I’m seeing “:25” on that line. I’m pretty sure I’m using port 587 instead of 25 for sending E-mails, because of an somehow unsolvable error.. Couldn’t be the issue, right? Since It sends to Gmail correctly.
Besides seeing a lot of ‘relay access denied’ in the log itself (elsewhere) I really haven’t got a clue what could be the issue.
Hopefully this issue could be solved soon, since I’m launching there website soon (promised today..), but there are a few contact forms that should be working. So while Hotmail accounts aren’t 'accessible’, the site cannot be launched..
Any help is appreciated much!
