If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This is not a general Postfix help forum - this is for the separate package PostfixAdmin which configures/maintains virtual domains & mailboxes using Postfix (plus MySQL or PostgreSQL, optionally maildrop, and Courier or Dovecot).
For Postfix help you should head over to postfix.org and check out the Postfix mailing lists.
But the problem is fairly common - Yahoo and AOL are also fairly strict in this. All it needs is for a few users to click "this is spam" when they've just forgotten they signed up for something and you get blacklisted for a while.
The difference is that when sending from webmail, the headers (and quite possibly the content - Outlook defaults to HTML) is different - enough to make a difference between being over or under the spam threshold. All you can do is monitor what's going through your server, and make sure none of your users are spamming (either intentionally or due to a malware infection). As long as your server stays reasonably "clean", you'll find that the block will clear in a few days. But if you are sending spam, you'll find your output more and more throttled.

It might be your IP address is listed in a dns blacklist.
It might be that you don't have a reverse DNS record on your IP address.
It might be that your envelope or address From header is for an invalid domain, or you're trying to send 'From' a domain that has a strict SPF record.
