Good afternoon,

I am new Zimbra and am trying to setup Zimbra as a mail server for a small business.

I am unable to send outgoing mail to domains outside of my own, If I try to send via Outlook I get stuck in a auth loop, If I try to send via the webmail client it tells me the address was rejected.

I am running this on a Redhat Enterprise box, Thank you for any help you can provide!
