    503 error in Outlook?!

    Hi Folks

    Require urgent assistance please! Our entire operation is now unable to send mail. We can receive ok, but not send! I called our ISP to check if they blocked the ports or something, but after a simple ping, it was confirmed that the ports are all open and ok.

    We were able to send mail no problem until about two days ago....

    I receive the following message returned when I try to send a mail:

    Your message did not reach some or all of the intended recipients.
    Subject: FYI
    Sent: 12/05/2006 08:50
    The following recipient(s) could not be reached:
    'leon@biobox.co.za' on 12/05/2006 08:50
    503 valid RCPT command must precede DATA

    What does this mean?! Our e-mail clients are set up to log in prior to sending. I am now clueless. PLEASE ASSIST!

            Hi again!

            Thank you so much for all your assistance up to now...

            I have spoken to my ISP again and they have assured me that there are no blocks from their side. What should I be telling them to get the matter resolved as I am sure the problem lies with them.

            Kind regards,
            David
