This means that the recipient or the Trend Micro Email Reputation
Service is blocking you, and you might be able to resolve the issue
if you contact the recipient or his/her administrator using some
other means, i.e., a freemail account or phone call. You could try
postmas...@aflo.be, but I doubt that would get through.

See above. Apparently you are assuming that there is something wrong
in your Postfix install. While this is possible, nothing you showed
us here suggests that. I don't even know what basis you had for this
assumption.
Email deliverability issues are very difficult. While some discussion
of these issues is tolerated on here, it's not on topic here. We
cannot discuss YOUR issue because you didn't think you needed to
provide any information with this post.
My WAG: maybe you don't have good FCrDNS for your host. See:
http://en.wikipedia.org/wiki/Forward_Confirmed_reverse_DNS
Do note:
- This is not a Trend Micro nor aflo.be support forum
- There is no Trend Micro plugin for Postfix
