CDONTS error

Hello,

I have installed CDONTS on windows 2003 server a long time ago. It worked perfectly fine. This week, the messages are not sending anymore and they stay in the queue folder.

I checked the event viewer and it gives that error:

Message delivery to the host 'XX.XX.X.XXX' failed while delivering to the remote domain 'xx***********' for the following reason: The connection was dropped by the remote host.

I put x's to keep privacy. Can someone please help me with this?? I have no clue why it's not getting through now.

Note: Cdonts works fine because when I put TWO different email address in the TO: field that link to two different mail server, one responds and I get the message but for the other one, it gives the above error in the event viewer

Thanks
