while I was checking my Exchange Server 2003 event viewer I found this error:
Error: MARC4Core 6702
ugin SMTPSend reports exception.
SMTP Send: Connection to the server failed. Please check your SMTP server settings.
Additional info: Connection closed.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp
Could you please tell me what is that and what should I do for it?
