Hello,
I am frequently getting this message

'[email protected]' on 19/01/2011 16:30 Server error: '550 5.7.1 Unable to relay'

When I want to send an mail .

I moved to Outlook from Thunderbird, and this problem with Outlook is disheartening me and makes me want to go back to Thunderbird.

I can't find any solution over the internet. Can you tell what to do in this situation?

Thanks in advance.
