outlook 2000 does not send or forward emails

[MacS09]

I use Outlook 2000 ith Windows XP (prof), SP3 on a stand alone laptop. Since
yesterday, I am unable to forward emails or reply to them. Occasionally I can
still send new email. The forwarded email gets deposited in the Sent folder
and a message like the following gets deposited in my Deleted folder (I use
Spamblocker which hetherto has orked absolutely fine):
"Your message did not reach some or all of the intended recipients.

Subject: RE: FW: Advanced Income on Demand System
Sent: 13/02/2009 17:52

The following recipient(s) could not be reached:

'Sam Zammit' on 13/02/2009 17:53
No transport provider was available for delivery to this
recipient."

Closing everything down and rebooting has not remedied the problem.

I'd be extremely grateful for suggestions.

Disable Spamblocker and see if the behavior changes.
