Mail relay denied

Mail relay denied

Hey all,

I am experiencing a problem when adding mail accounts into VO.
Everything works fine in the VO workspace, i can both send and receive, but when i try to send an email from outlook, i get this response:

Your message did not reach some or all of the intended recipients.

Subject: Test
Sent: 4/2/2007 12:33 PM

The following recipient(s) could not be reached:
'olsen@*****.**' on 4/2/2007 12:33 PM
553 5.3.0 <olsen@*****.**>... We do not relay from 81.***.***.***








I have added this ip in my mail system as a valid relay ip.
Does this make sense to anyone? Have anyone inexperienced this?
(I am using Merak mail server btw.)

Jak.
