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.

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!
