I used to have zimbra setup to forward emails to my old hotmail, which is now upgraded to outlook. Outlook thinks all of my contacts are evil and sends them a 550 sc-001 error when I get an email from them saying the message is spam. Problem is I can't stop this forwarding from zimbra, even though I don't see the outlook account in my forwarding anymore and it is not setup as a filter to forward. Is there any other thing I can try to stop zimbra from forwarding to my outlook?

I don't really know who to talk to about this, outlook seems unhelpful.
