Could you search on transport logs about this connection? This will give up more information (host unreachable, drop connection)

Thanks.

the domain is madpark.com , I am sending email to tom@madpark.com

they have their mx record , if you  can double check , I am getting TLS_Srv:207.173.178.165 error

when sending email to that domain
Is this really Exchange or is it Lotus/Sendmail ?

Do you have a SendConnector for this domain ? If so was it recently modified or some changes done ?
